Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

To design a short circuit stub network at 2 GHz for matching a 50 Ω microstrip transmission line with the load ZL = 13-6j, we can use a shunt stub matching technique. This method consists of adding a short-circuited transmission line (the stub) in parallel with the main transmission line to achieve impedance matching.

First, normalize the load impedance ZL by dividing it by the characteristic impedance Z0 (50 Ω):
ZL_normalized = (13-6j)/50 = 0.26-0.12j
Next, plot this normalized impedance on a Smith chart and find the corresponding reflection coefficient, Γ.
Now, let's find the distance (d) from the load to the point where the stub needs to be connected. To do this, move towards the generator on the Smith chart until you reach a point with a purely real impedance. This distance, d, is expressed in wavelengths or electrical degrees.For the short circuit stub, find the length (l) needed to obtain a purely imaginary admittance at the connection point. This length can also be expressed in wavelengths or electrical degrees. Calculate the physical length of the stub using the relation: physical length = (wavelength x electrical length) / 360With the values of d and l, you can design the short circuit stub network at 2 GHz to match the 50 Ω microstrip transmission line with the given load. Note that the performance of the matching network is frequency-dependent, and it's optimized for a design frequency of 2 GHz.

Explanation:

I thought all of them are networking devices

During operations outside controlled airspace at altitudes of more than 1,200 feet AGL (Above Ground Level) but less than 10,000 feet MSL (Mean Sea Level), the minimum distance below clouds requirement for VFR (Visual Flight Rules) flight at night is not specified in a fixed value or regulation. The specific requirement may vary depending on the jurisdiction and local regulations.

The minimum distance below clouds requirement for VFR flight at night is typically determined by the governing aviation authority of the specific country or region. While there are general guidelines and recommendations for VFR flight, such as maintaining a minimum of 500 feet vertical separation from clouds during the day, there may not be a specific requirement for VFR flight at night regarding the distance below clouds.

Aviation authorities often focus on providing guidelines for maintaining adequate visibility and avoiding instrument meteorological conditions (IMC) during night VFR flight. Pilots are generally encouraged to maintain a safe margin from clouds to ensure visual reference to the ground and surrounding airspace.

It is important for pilots to consult the specific regulations and guidelines of their jurisdiction, as well as consider weather conditions and any local restrictions or airspace classifications that may apply when conducting VFR flight at night. Following proper procedures and exercising good judgment is essential to ensure safe and compliant operations.

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

To calculate the required processing and assembly operations, workers, and total floor space for the new factory, we can break down the problem into smaller parts and analyze each element.

(a) Processing and assembly operations:

Number of components made in the factory: 250 components * 35% = 87.5 (round up to 88 components)

Processing operations for components: 88 components * 8 processing operations = 704 processing operations

Assembly operations for final product: 1 assembly operation (as each product is assembled in one workstation)

Total operations = 704 processing operations + 1 assembly operation = 705 operations

(b) Number of workers (direct labor only):

Processing workers: 704 processing operations / 1 (one worker per work cell) = 704 workers

Assembly workers: 13 models * 1000 units/model = 13,000 units/year

Assembly time per unit: 48 min/unit = 0.8 hr/unit

Assembly time for all products: 13,000 units * 0.8 hr/unit = 10,400 hr

Assembly workers required: 10,400 hr / 2,000 hr/shift = 5.2 (round up to 6 workers)

Total workers = 704 processing workers + 6 assembly workers = 710 workers

(c) Total floor space required:

Processing floor space: 704 work cells * 25 m2/cell = 17,600 m2

Assembly floor space: 6 workstations * 25 m2/station = 150 m2

Total production area: 17,600 m2 + 150 m2 = 17,750 m2

Additional allowance (45%): 17,750 m2 * 45% = 7,987.5 m2

Total floor space = 17,750 m2 + 7,987.5 m2 = 25,737.5 m2 (round to 25,738 m2)

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

To determine the total quantity of nitrogen (N2) needed to fill a vehicle's four tires to a gage pressure 4 x 0.6 m3 x (180 kPa + 1 atm) x 0.028 kg/L x 0.028 kg/L = 48.48 kg is the needed mass of N2.

We must first know the capacity of each tire, which is 0.6 m3, in order to calculate the total amount of nitrogen (N2) needed to inflate all four tires of a car to a gage pressure of 180 kPa at a temperature of 25oC. The total pressure in each tire is 181 kPa when the ambient pressure of 1 atm is taken into account. The number of moles of nitrogen in each tire may then be determined using the ideal gas equation, PV = nRT, where n denotes the number of moles, R denotes the ideal gas constant, T is the temperature in Kelvin, and P and V denote the pressure and volume of the tire, respectively. We can determine the mass of nitrogen using its molar mass (28 g/mol).

Answer:

B.  1.75 microfarads

Explanation:

When capacitors are connected in parallel, the total capacitance is equivalent to the sum of each individual capacitor's capacitance.

With this in mind, we have the values, 0.1, 0.6, 1.0, and 0.05, all microfarads.  So simply, we need to sum these values.

0.1 + 0.6 + 1.0 + 0.05

= 0.7 + 1.0 + 0.05

= 1.7 + 0.05

= 1.75

So the total capacitance for this circuit would be 1.75 microfarads.

B. ability to press down and become solidly fixed in the ground.

C. relative weight of a block of stone to its size.

D. force a block exerts on the blocks around it.

Answer:

A. ability to support pressure without breaking.

Explanation:

Stone has been used as a building material since ancient times because of its compressive strength, which is the ability to support pressure without breaking.

Compressive strength can be defined as the ability of a structural element or particular material to withstand an applied, which is aimed at reducing the size of the structural element.

Simply stated, it is the ability of a structural element or material to withstand an applied load without deflections, fracture or having any crack.

In this context, a stone possesses the ability to resist or withstand compression loads.

Some examples of other materials or structural elements having good compressive strength are steel, bones, concrete etc. The standard unit of measurement of the compressive strength of a material is Mega Pascal (MPa) or pound-force per square inch (psi) in the United States of America.

Answer: 75,000 Hz

Explanation:

To calculate the frequency of the supply voltage, we need to use the formula:

frequency = 1 / time period

where the time period is the time it takes for one complete cycle of the waveform. For a sine wave, the time period is given by:

time period = 2π / angular frequency

where the angular frequency is the rate of change of the angle with respect to time and is given by:

angular frequency = 2π × frequency

Comparing the given voltage expression v = 240 sin (471,239t) V to the general form of a sine wave:

v = Vm sin(ωt + θ)

where Vm is the amplitude, ω is the angular frequency, t is time, and θ is the phase angle, we can see that the amplitude is 240 V, the angular frequency is 471,239 rad/s, and there is no phase angle (θ = 0).

Using the formula for angular frequency, we can find the frequency:

angular frequency = 2π × frequency

471,239 = 2π × frequency

frequency = 471,239 / (2π) ≈ 75,000 Hz

Therefore, the frequency of the supply voltage is approximately 75,000 Hz.
