Explanation:

The statement is false, as the term "rem" does consider the biological effect of different kinds of radiation from the same dose in rads.

The term "rem" (Roentgen equivalent in man) does take into consideration the biological effect of different kinds of radiation from the same dose in rads. The rem is a unit of equivalent dose, which accounts for the varying levels of biological damage caused by different types of ionizing radiation. It is calculated by multiplying the absorbed dose in rads by a quality factor specific to the type of radiation in question, thus accounting for their differing biological effects.

A strain gauge should have a low stiffness in order to get high sensitive readings. This is because a strain gauge is designed to measure small changes in length or deformation in a material due to external forces, and a low stiffness allows for greater flexibility and sensitivity to these changes.

A strain gauge is a type of sensor that is used to measure the deformation or strain of a material. It consists of a thin wire or foil that is bonded to the surface of the material being measured. When the material is deformed due to an external force, the wire or foil also stretches or compresses, causing a change in resistance. This change in resistance can be measured and used to calculate the strain or deformation of the material. The sensitivity of a strain gauge is determined by its stiffness, which is the resistance of the wire or foil to deformation. A strain gauge with a high stiffness will be less sensitive to small changes in deformation, while a strain gauge with a low stiffness will be more sensitive to these changes. Therefore, in order to get high sensitive readings from a strain gauge, it should have a low stiffness. This will allow it to detect even small changes in deformation, which can be useful in applications such as structural monitoring or strain testing.

The continental margin is composed of the following three zones: the continental shelf, the continental slope, and the continental rise.

The zone between the ocean floor and the continental slope is known as the continental margin. It is the underwater section of a continent that contains the continental shelf, continental slope, and continental rise.

The Continental Shelf: It is the sloping extension of the continent into the ocean. It starts at the coastline and goes all the way to the continental slope. The continental shelf's breadth is determined by how gently the continent slopes downward into the ocean.

The Continental Slope: The continental slope, as the name implies, is a steep slope that leads down to the ocean floor. The incline is between 3° and 6°. The slope of the continental slope is steeper than that of the continental shelf.

The Continental Rise: It is a gently sloping sediment-covered area that links the continental slope to the deep-ocean floor. The continental rise is a result of the accumulation of sediment that falls off the continental shelf and slope over time.

The radius of gyration of the hollow drive shaft with an inside diameter of 3 inches and an outside diameter of 3.5 inches is approximately 1.80 inches.

The formula for the radius of gyration is:

r = √(I / m)

Here,

I is the moment of inertia

m is the mass of the drive shaft.

To calculate the moment of inertia of a hollow drive shaft, use the following formula:

I = (π/4) × [(R² + r²) - (r²)]

where

R is the outer radius

r is the inner radius of the shaft.

We have:

Inner diameter = 3 inches

Outer diameter = 3.5 inches

Length of the shaft = 6 ft = 72 inches

Mass of the shaft = 25 lbs

Rotational speed = 500 rpm

Inner radius, r = 3/2 = 1.5 inches

Outer radius, R = 3.5/2 = 1.75 inches

Mass of the shaft, m = 25/32.2 = 0.776 kg (since the acceleration due to gravity is 32.2 ft/s²)

Using the above values in the formula for the moment of inertia,

I = (π/4) × [(1.75² + 1.5²) - (1.5²)]

 = 4.970 kg.m²  (approx.)

Now, using the formula for the radius of gyration,

r = √(I / m)

 = √(4.970 / 0.776)

 = 1.80 inches (approx.)

Answer:

the answer is 180mm

Explanation:

the answer is 180mm.

When the string of a helium balloon slips from your hand and rises into the air, the balloon rises until it reaches an altitude where its weight equals that of the same volume of air.

When a helium balloon is released, it rises until it reaches an altitude where its weight equals that of the same volume of air. This is due to the principle of buoyancy.

Helium gas is lighter than air, which causes the balloon to initially ascend. As the balloon rises, the surrounding air pressure decreases, and so does the density of the air. Eventually, the balloon reaches an altitude where the density of the surrounding air matches the density of the helium-filled balloon.

At this point, the upward buoyant force acting on the balloon becomes equal to the downward gravitational force (weight) acting on the balloon. This balance of forces causes the balloon to stop rising further and instead float at a relatively stable altitude.

Option c) accurately describes this behavior, where the balloon rises until it reaches an altitude where its weight equals that of the same volume of air.

The question should be:

The string of a helium balloon slips from your hand and rises into the air. when this happens

a) the balloon rises indefinitely because helium is lighter than air

b) the balloon rises until it reaches an altitude where the air and helium densities are equal.

Therefore, the stress level at which fracture will occur for a critical internal crack length of 5 mm is approximately 22.53 MPa.

To compute the stress level at which fracture will occur for a critical internal crack length of "c2," we can use the formula for stress intensity factor:

K = Y * σ * √(π * c)

Where:

K is the stress intensity factor

Y is the geometric factor (typically assumed to be 1 for internal cracks)

σ is the applied stress

c is the crack length

We can rearrange the formula to solve for the stress (σ):

σ = K / (Y * √(π * c))

Given the values:

Stress at fracture (σ1) = 100 MPa

Critical internal crack length (c1) = 1 mm

New critical internal crack length (c2) = 5 mm

Let's calculate the stress level (σ2) for the new critical crack length:

σ2 = (100 MPa) / (1 * √(π * 5 mm))

= 100 MPa / (√(15.71 mm))

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.

The combustion air feed for the process should be controlled at 19% excess air to achieve a 27% cumene conversion and 96% selectivity to CHP (cumene hydroperoxide). The vent should only contain nitrogen and excess air.

The temperature for the reaction must be in the range of 220-232°C to ensure complete conversion and high selectivity. Additionally, the molar ratio between cumene and oxygen needs to be carefully monitored, as a ratio too high will lead to low conversion, and a ratio too low will lead to low selectivity. The pressure of the reaction should also be controlled in order to ensure the desired conversion and selectivity. The pressure should be kept at around 1.3-1.5 bar. Finally, the vent should only contain nitrogen and excess air in order to minimize the risk of explosions.

Both Technician A and Technician B are correct in their statements.

Technician A is correct in stating that engine vacuum is typically measured in inches of mercury (in. Hg).

Engine vacuum refers to the difference in pressure between the inside and outside of the engine. It is commonly measured using a vacuum gauge, and the unit of measurement is inches of mercury.

The vacuum gauge displays the amount of vacuum present in the engine by measuring how far the pressure deviates below atmospheric pressure, which is typically expressed in inches of mercury.

Technician B is also correct in stating that a pressure gauge labeled psig (pounds per square inch gauge) will read 14.7 psi (pounds per square inch) at sea level.

The abbreviation "psig" indicates that the pressure is measured relative to atmospheric pressure. At sea level, atmospheric pressure is approximately 14.7 psi.

Therefore, a pressure gauge labeled psig will read 14.7 psi when the pressure being measured is equal to atmospheric pressure.

The given statement is false. The "something a person has" authentication mechanism does not utilize biometrics but instead relies on physical objects or tokens possessed by the user.

The "something a person has" factor in authentication refers to the possession of a physical object that is unique to the individual and can be used to verify their identity. Examples of such objects include smart cards, key fobs, security tokens, or electronic devices like smartphones.

Unlike biometric authentication, which relies on the inherent physical or behavioral characteristics of the user, the "something a person has" approach focuses on the physical possession of an item that can be used for authentication purposes. The user presents or uses the physical object as evidence of their identity, typically by entering a unique code, using a security chip, or generating a one-time password.

This authentication mechanism is often used in combination with other factors such as passwords (something a person knows) or biometrics (something a person is) to create a multi-factor authentication (MFA) system. By combining different factors, MFA provides an additional layer of security to ensure that the person accessing the system or service is indeed the authorized user.

Answer:

-2 and 6

Explanation:

Let "x" and "y" be 2 numbers.

The sum of the two numbers is 4. The mathematical expression is:

x + y = 4

y = 4 - x   [1]

The sum of their squares minus three times their product is 76. The mathematical expression is:

x² + y² - 3 x y = 76   [2]

If we substitute [1] in [2], we get:

x² + (4 - x)² - 3 x (4 - x) = 76

x² + 16 - 8 x + x² - 12 x + 3 x² = 76

5 x² - 20 x - 60 = 0

We apply the solving formula for second order equations and we get x₁ = 6 and x₂ = -2.

If we replace these x values in [1], we get:

y₁ = 4 - x₁ = 4 - 6 = -2

y₂ = 4 - x₂ = 4 - (-2) = 6

As a consequence, one of the numbers is 6 and the other is -2.

A material's ductility refers to its capacity to withstand plastic deformation or drawing without breaking. As a result, it provides information on how "soft" or pliable the material is. The types and concentrations of alloying elements present affect the ductility of steels in different ways.

A material's susceptibility to drawing is referred to as a mechanical attribute as ductility. The degree to which a material can withstand plastic deformation under tensile stress before failing is known as ductility in the field of materials research. In engineering and manufacturing, ductility is a crucial factor.

Glass, ceramic, graphite, and certain alloys with very low plasticity are examples of brittle materials. In these materials, fractures can start without plastic deformation and quickly progress to brittle breaking.

Diameter of the materials are 0.505 in

Diameter after appling tension in each material 0.484, 0.398 and 0.253 in

Initial length of the materials are 2 in

Length after appling tension in each material 2.13, 2.48 and 2.78 in

We can observe that the first material is not elongating that much as well as is not changing its diameter that much so the material can be classified as Brittle.
