Answers

Answer 1

buckling. The buckling capacity of the beam becomes the limiting factor in determining the size of the beam.

What is the role of buckling capacity of the beam?

The choice of size is made such that the beam will not buckle under the expected loads and will have sufficient strength to carry those loads safely. The length and slenderness ratio of the beam also play a role in determining the buckling capacity, and these factors must be considered when selecting the size of a heavily loaded, steel beam with deep proportions.

Sizing of heavily loaded steel beams with deep proportions is controlled by buckling, which occurs when the beam is subjected to compression loads. The beam's buckling capacity determines its size and strength to carry the expected loads without failure. The length and slenderness ratio of the beam also affect buckling, which must be taken into account when selecting the beam size.

The block diagram of the network consists of various components and connections that enable the functioning of the 8-bit binary counter based on the 74LS16x family.

What are the input and output signals of the blocks in the block diagram, and what are the tasks of each box in terms of signal processing?

The logical network of the boxes in the block diagram involves the use of MSI circuits, such as the 4-bit parallel adder, 4-bit cascadable comparator, and 4-bit 7416x binary up-counter, along with the necessary number of logic gates and flip-flops. The input signals of the blocks in the block diagram include the clock signal, control signals, and data signals. The clock signal is used to synchronize the operations of the counter, while the control signals determine the specific sequence and timing of the output values. The data signals represent the binary values that are processed and propagated through the counter.

The tasks of the boxes in the block diagram involve performing specific operations on the input signals to generate the desired output sequence. For example, the 4-bit parallel adder can be used to increment the binary count by one, while the cascadable comparator can be utilized to compare the current count with predefined values to trigger specific actions. The 7416x binary up-counter can be employed to maintain the count and propagate it to subsequent stages.

In addition to these MSI circuits, logic gates such as NAND, NOR, AND, OR, XOR, and XNOR, as well as flip-flops like SR, JK, D, and T, are used to implement the necessary logic operations and sequential behavior within the counter.

Answers

The weight of this astronaut on the spring scale is equal to 25.5 lbf.The weight of this astronaut on the beam scale is equal to 150-lbf.

Given the following data:

Mass of astronaut = 150-lbm.

Acceleration due to gravity on Moon = 5.48 ft/s².

What is weight?

Weight can be defined as the force acting on an object or a physical body due to the effect of gravity. Also, the weight of a physical object (body) is typically measured in Newton or ounces.

How to calculate the weight of this astronaut?

Mathematically, the weight force on a physical body can be calculated by using this formula:

W = mg

Where:

W represents the weight.m represents the mass.g represents the acceleration due to gravity.

Substituting the given parameters into the formula, we have;

Weight = 150 × 1/32.2 × 5.48

Weight = 25.5 lbf.

For the weight on beam scale.

A beam scale is a measuring instrument that is designed and developed to compare the masses of a physical body and as such, it's not affected by the variations in acceleration due to gravity. Therefore, the beam scale would read 150-lbf as it read on earth.

The question is incomplete. The complete question is :

The hydrofoil boat has an A-36 steel propeller shaft that is 100 ft long. It is connected to an in-line diesel engine that delivers a maximum power of 2590 hp and causes the shaft to rotate at 1700 rpm . If the outer diameter of the shaft is 8 in. and the wall thickness is \($\frac{3}{8}$\)  in.

A) Determine the maximum shear stress developed in the shaft.

\($\tau_{max}$\) = ?

B) Also, what is the "wind up," or angle of twist in the shaft at full power?

\($ \phi $\) = ?

Solution :

Given :

Angular speed, ω = 1700 rpm

                              \($ = 1700 \frac{\text{rev}}{\text{min}}\left(\frac{2 \pi \text{ rad}}{\text{rev}}\right) \frac{1 \text{ min}}{60 \ \text{s}}$\)

                              \($= 56.67 \pi \text{ rad/s}$\)

Power \($= 2590 \text{ hp} \left( \frac{550 \text{ ft. lb/s}}{1 \text{ hp}}\right)$\)

          = 1424500 ft. lb/s

Torque, \($T = \frac{P}{\omega}$\)

                 \($=\frac{1424500}{56.67 \pi}$\)

                 = 8001.27 lb.ft

A). Therefore, maximum shear stress is given by :

Applying the torsion formula

\($\tau_{max} = \frac{T_c}{J}$\)

        \($=\frac{8001.27 \times 12 \times 4}{\frac{\pi}{2}\left(4^2 - 3.625^4 \right)}$\)

      = 2.93 ksi

B). Angle of twist :

     \($\phi = \frac{TL}{JG}$\)

         \($=\frac{8001.27 \times 12 \times 100 \times 12}{\frac{\pi}{2}\left(4^4 - 3.625^4\right) \times 11 \times 10^3}$\)

This breaking bad, fly-by-night company is on a shoestring budget and has very little money to purchase equipment. Fortunately, cousin Bemie has a reactor surplus company and get reactors for them. The reaction AB+C takes place in the liquid phase. Below is the Levenspiel plot for this reaction. You have up to $10,000 to use to purchase reactors from those given below. Reactor Type Number Volume (dm) Cost CSTR 2 2 $1.000 CSTR 4 $2,000 PFR $2.000 CSTR $4,000 CSTR 58.000 01 02 03 04 05 06 07 08 0.9 PER 2 12 56,000 What reactors do you choose, how do you arrange them, and what is the highest conversion you can get for S10,000? Approximately what is the corresponding highest conversion with your arrangement of reactors? Scheme and sketch your reactor volumes.

Answers

The chosen reactors and their arrangement can achieve the highest possible conversion within the given budget of $10,000.

To achieve the highest conversion with a budget of $10,000, we need to choose the reactors with the lowest cost per volume and arrange them in a way that maximizes the conversion. From the given options, the CSTR reactors with a cost of $1,000 and $2,000 have the lowest cost per volume. We can purchase two of the $1,000 CSTR reactors and one of the $2,000 CSTR reactors for a total cost of $4,000. We can then use the remaining $6,000 to purchase three of the $2,000 PFR reactors.

The arrangement of the reactors should be as follows:
- The two $1,000 CSTR reactors should be placed in series to achieve a higher conversion.
- The $2,000 CSTR reactor should be placed in series with the two $1,000 CSTR reactors to further increase the conversion.
- The three $2,000 PFR reactors should be placed in series with the CSTR reactors to achieve the highest possible conversion.

The highest conversion that can be achieved with this arrangement of reactors is approximately 0.8, as shown in the Levenspiel plot. The corresponding highest conversion with this arrangement of reactors is approximately 0.8.

The reactor volumes can be sketched as follows:
CSTR (2 dm) -> CSTR (2 dm) -> CSTR (4 dm) -> PFR (2 dm) -> PFR (2 dm) -> PFR (2 dm)

Overall, the chosen reactors and their arrangement can achieve the highest possible conversion within the given budget of $10,000.

In compliance with NEC 408.4, the method used to prepare directories in panelboards can vary. Two common approaches are either using a pencil to mark the circuit directory or having it typed up for a neater and easier-to-read presentation.

The choice between using a pencil to mark the circuit directory or having it typed up depends on personal preference, project requirements, and local regulations. Both methods have their advantages and considerations. Using a pencil to mark the circuit directory allows for flexibility and easy modification. It enables quick updates or changes to be made directly on the directory, especially when there are frequent additions or modifications to the circuits. However, it may be less visually appealing and can become illegible over time due to erasures or smudging. Having the circuit directory typed up provides a neat and professional appearance. It ensures legibility and easier comprehension of the information. A typed directory is also easier to update and maintain consistency across multiple panelboards. However, it may require more time and effort to create and update, especially if there are frequent changes to the circuits. Ultimately, the choice between these methods depends on the specific project requirements, individual preferences, and the level of importance given to factors such as legibility, ease of modification, and overall presentation.

4. A cylindrical specimen of a brass alloy 7.5 mm in diameter and 90.0 mm long is pulled in tension with a force of 6000 N; the force is subsequently released. a. Compute the final length of the specimen. b. Compute the final specimen length with the load is increased to 16,500 N and then released.

Answers

The elastic properties of the brass specimen enables it to return to its

original length when stressed below the yield strength.

The correct responses are;

4. a. The final length is 90.0 m.

b. The final length is 97.2 mm.

Reasons:  

a. Diameter of the brass alloy = 7.5 mm

Length of the specimen = 90.0 mm

Force applied = 6000 N

The equation for the applied stress, σ, is presented as follows;

\(\sigma = \dfrac{Force \ applied}{Area \ of \ specimen} = \dfrac{6000 \, N}{\pi \cdot \left(\dfrac{7.5 \times 10^{-3}}{2} \, m} \right)^2 } \approx 135.81 \ \mathrm{MPA}\)

Depending on the cold working condition, 135.81 MPa is below the yield

strength, and the brass will return to its original condition when the force is

removed. The final length is remains as 90.0 m.

b. When the applied force is F = 16,500 N, we have;

\(\sigma = \dfrac{16,500\, N}{\pi \cdot \left(\dfrac{7.5 \times 10^{-3}}{2} \, m} \right)^2 } \approx 373.48\ \mathrm{MPA}\)

The stress found for the force of 16,500 N is above the yield stress of

brass, and it is therefore, in the plastic region.

From the stress strain curve, the strain can be estimated by drawing a line

from the point of the 373.48 MP on the stress strain curve, parallel to the

elastic region to intersect the strain axis, which gives a value of strain

approximately, ε = 0.08.

The length of the specimen is given by the formula; \(l_i = l_0 \cdot (1 + \epsilon)\)

Therefore;

\(l_i\) = 90 × (1 + 0.08) = 97.2

The final length of the specimen, \(l_i\) = 97.2 mm

When the voltages between the three phases are not equal, the current increases dramatically in the motor winding's, and if allowed to continue, the motor will be damaged.

Explanation:

All of these are true about GMA (MIG) welding EXCEPT that:
O both the base metal and electrode are melted.
O shielding gas protects the well, tiom contamination.
O heat is produced using a short electric arc.
the welding gun liner regulates the shielding gas.

Answers

Answer:

the welding gun liner regulates the shielding gas.

Explanation:

The purpose of the welding gun liner is to properly position the welding wire from the wire feeder till it gets to the nozzle or contact tip of the gun. Regulation of the shielding gas depends on factors such as the speed, current, and type of gas being used. In gas metal arc welding, an electric arc is used to generate heat which melts both the electrode and the workpiece or base metal.

The electric arc produced is shielded from contamination by the shielding gas. The heat generated by the short electric arc is low.

Many of the problems applied scientists address are multidisciplinary issues and therefore require the collaboration of scientists with a variety of skills and knowledge. Explain which types of scientists might be involved in studying global warming.

Answers

Scientists have studied global warming for more than 100 years. Thousands of experts have tested hypotheses, gathered evidence, constructed models, debated results, and reviewed one another’s work. Thousands of papers are written every year, produced from nearly every leading university and research institution on Earth—from Harvard to NASA and the US Department of Defense.

The consensus couldn’t be clearer. Climate change is happening. It’s caused primarily by the burning of oil, gas, and coal. If we do nothing, the world will become significantly less habitable.

We’ve lost precious time, but if we act now—decisively and dramatically—we still have a chance at avoiding climate change’s most catastrophic impacts

Using a compound interest of 10%, find the equivalent uniform annual cost for a proposed machine that has a first cost of P120,000 an estimated salvage value of P35,000 and an estimated economic life of 10 years. Annual maintenance will amount to P2,500 a year and periodic overhaul costing P5,000 each will occur at the end of the fourth and eight year

Answers

The equivalent uniform annual cost for the proposed machine is P26,212.25.

To calculate the equivalent uniform annual cost, we need to add up all the costs and salvage value and then calculate the equivalent annual payment over the economic life of the machine using the compound interest formula.

In this case, the total cost is P142,500 (P120,000 first cost + P25,000 maintenance + P10,000 overhaul - P13,500 salvage value). Using a compound interest rate of 10%, the equivalent uniform annual cost is P26,212.25.

The equivalent uniform annual cost provides a way to compare the costs of different machines or projects with different cash flows over their economic life. It represents an equal annual payment that would result in the same total cost as the proposed machine.

By calculating the equivalent uniform annual cost, we can determine if the machine is a good investment in terms of cost and benefit.

which activity promotes the preservation of species

Answers

Answer:

A

Explanation:

In-situ conservation is the practice of keeping living things in their natural habitats. In the process, the natural surroundings or ecosystem is preserved and protected in order to benefit and conserve all the constituent species, whether they are known or undiscovered.

What activity promotes the preservation of species?

Wildlife conservation helps to maintain and preserve many species of animals, plants, and their natural habitats. If we keep protecting wildlife, future generations will be able to enjoy our natural world and the incredible creatures that live there.

A fantastic method to protect the natural habitat of nearby animals is to grow native plants in your garden or on any land you own. In addition to benefiting the animals' population, this helps prevent the spread of exotic species, which harms the local fauna.

Therefore, In-situ conservation activity promotes the preservation of species.
