Both technicians are correct in some rack and pinion steering gears.

What do you mean by steering gear?

The steering gear is a device that converts the steering wheel's rotating motion into straight line motion of the linkage. The steering gears are contained in a box known as the steering gear box. Because the steering wheel is directly connected to the steering linkage, moving the front wheels would be difficult. As a result, a reduction mechanism is used to aid the driver.

Some rack and pinion steering gears have an adjusting screw to set pinion bearing preload, and some steering gears have adjustment shims.

Answer:

D) Lower efficiency and lower effectiveness.

Explanation:

Given;

Two finned surfaces with long fins which are identical,

with difference in the convection heat transfer coefficient,

The first finned surface has a higher convection heat transfer coefficient, but gives the same heat rate as the second, which will make it (first finned surface) to have lower efficiency and lower effectiveness than the second finned surface.

Therefore, the correct option is "(D) Lower efficiency and lower effectiveness"

In a drained triaxial test, the soil specimen is subjected to a confining pressure while being sheared. For a normally consolidated clay specimen, the results of the test can be used to determine the soil friction angle.

First, we need to calculate the mean effective stress, σ'm, using the equation:

σ'm = (3/2)Pc

where Pc is the chamber-confining pressure.

σ'm = (3/2)(125kN/m2)
σ'm = 187.5kN/m2

Next, we can calculate the deviator stress, σ'd, using the equation:

σ'd = σ'1 - σ'm/3

where σ'1 is the major principal stress.

σ'd = 175kN/m2 - 187.5kN/m2/3
σ'd = 175kN/m2 - 62.5kN/m2
σ'd = 112.5kN/m2

Finally, we can calculate the soil friction angle, ϕ', using the equation:

tan ϕ' = σ'd/σ'm

tan ϕ' = 112.5kN/m2 / 187.5kN/m2
ϕ' = tan-1 (0.6)
ϕ' = 31.6°

Therefore, the soil friction angle for the given normally consolidated clay specimen is approximately 31.6°.

Hello! I'm happy to help you with your question. In order to determine the soil friction angle (ϕ') for a normally consolidated clay specimen, we'll use the results of a drained triaxial test. Here are the given values:

Chamber-confining pressure (σ3) = 125 kN/m²
Deviator stress at failure (Δσ) = 175 kN/m²

Step 1: Calculate the major principal stress (σ1) at failure
σ1 = σ3 + Δσ
σ1 = 125 kN/m² + 175 kN/m²
σ1 = 300 kN/m²

Step 2: Determine the stress ratio (R) at failure
R = (σ1 - σ3) / (σ1 + σ3)
R = (300 kN/m² - 125 kN/m²) / (300 kN/m² + 125 kN/m²)
R = 175 kN/m² / 425 kN/m²
R ≈ 0.4118

Step 3: Calculate the soil friction angle (ϕ')
ϕ' = sin^(-1)(R)
ϕ' = sin^(-1)(0.4118)
ϕ' ≈ 24.5°

So, for the normally consolidated clay specimen, the soil friction angle (ϕ') is approximately 24.5° based on the results of the drained triaxial test.

The relationship between density, pipe average velocity, and cross-sectional area perpendicular to the velocity can be used to calculate mass flow rate.

The quantity of mass flowing across a cross-section per unit of time is known as the mass flow rate. The volume of the fluid moving through a cross-section per unit time is referred to as a volume flow rate. By multiplying the fluid's density, the average pipe velocity, and the cross-sectional area of the pipe normal to the velocity, one can compute the mass flow rate, which is a measurement of the amount of mass flowing through a particular cross-section per unit time. Contrarily, volume flow rate is defined as the amount of fluid moving across a specific cross-section in a unit of time. The mass flow rate into a control volume is proportional to the velocity component parallel to the cross-sectional area for fluid flow in a pipe, when the velocity is constant across the pipe's cross-section.

No, the size of a fish tank does not determine how large a fish will grow. Fish will continue to grow according to their genetic engineering and can only grow to a certain size given their species and individual genetic makeup.

However, the size of the fish tank can affect the growth and health of the fish. If the tank is too small, the fish may become stressed and unable to move around freely, which can lead to stunted growth and potential health problems. In addition, a small tank can lead to poor water quality due to the buildup of waste and toxins, which can also negatively impact the growth and health of the fish.

Therefore, it is important to provide an appropriately sized tank for the species of fish being kept, taking into consideration factors such as their adult size, swimming behavior, and social requirements. Providing a spacious and well-maintained environment can help to promote the healthy growth and development of the fish.

Answer: Chemical!!!

Explanation:

a) Number of unit cells = 2.39 × 10²² unit cells.

b) Number of iron atoms =4.78 × 10²² iron atoms.

(a) The density of BCC iron is ρ = 7.87 g/cm³. The volume of a unit cell of BCC structure is V = a³/2.

The edge length a of the BCC unit cell can be calculated from the density ρ of the iron and the atomic mass of iron.

At. mass = (6.02 × 10²³ atoms/mol)(55.85 g/mol) = 3.33 × 10²⁵ atoms

The mass of one unit cell can be obtained by multiplying the density of iron by the volume of the unit cell.

Mass of unit cell = Density × Volume= 7.87 g/cm³ × (2.866 × 10⁻⁸ cm)³ / 2= 2.47 × 10⁻²⁴ g

The number of unit cells can be calculated by dividing the total mass of the paper clip by the mass of one unit cell.

Number of unit cells = 0.59 g / 2.47 × 10⁻²⁴ g/unit cell≈ 2.39 × 10²² unit cells

(b) One unit cell contains two atoms of iron, since there is one atom at each corner of the cube and each atom is shared with eight neighboring unit cells. Therefore, the total number of iron atoms in the paper clip is the number of unit cells multiplied by two.

Number of iron atoms = 2 × Number of unit cells= 2 × 2.39 × 10²²≈ 4.78 × 10²² iron atoms.

Answer: a) 2.39 × 10²² unit cells. b) 4.78 × 10²² iron atoms.

Answer:

Overall project duration

Explanation:

Scheduling can best be defined as the process used to determine a overall project duration.

Answer:

Mach number = 0.68168

The flow should be treated as compressible.

Explanation:

Given that:

The altitude of a commercial jet = 35000

The properties of air at that given altitude are as follows:

Pressure = 24.577 kPa

Temperature T = 50.78176° C

Temperature T = ( 50.78176 + 273 )K = 328.78176 K

\(\varphi = 0.38428 \ kg/m^3\)

The velocity is also given as: 550 mph = 245.872 m/s

Therefore, the sonic velocity is firstly determined by using the formula:

\(a = \sqrt{ \vartheta \times R \times T\\)

\(a = \sqrt{1.4 \times 287 \times 323.78176\)

\(a = \sqrt{130095.5112\)

a = 360.68755 m/s

Then, we can calculate the Mach number by using the expression:

\({Mach \ number = \dfrac{V}{a}}\)

\(Mach \ number = \dfrac{245.872}{360.68755}\)

Mach number = 0.68168

b) Ideally, all flows are compressible because the Mach number is greater than 0.3, suppose the Mach number is lesser than 0.3, then it is incompressible.

1) The two measures used in rating the size of an injection molding machine are the clamping force and the shot capacity. The clamping force refers to the force exerted by the machine to keep the mold closed during the injection process.

2) Packing the mold involves applying additional pressure to the resin after the injection phase. This is done to ensure that the mold cavity is completely filled and that the plastic material is properly packed within the mold. Good packing is important because it helps to eliminate voids, reduce shrinkage, and improve the overall strength and quality of the injection molded parts.

3) High crystallinity in a resin affects the injection molding process and post-molding operations. Resins with high crystallinity tend to have slower melt flow rates, requiring higher processing temperatures and longer cooling times.

4) It is important to have uniform thickness in the sections of a molded part to ensure consistent cooling and minimize the risk of defects.
5) To determine the clamping force required, we multiply the part cross-sectional area (10 x 14 inches) by the general rule of 2.5 tons of force per square inch.

6) Low specific heat capacity is desired in a mold cavity material for some applications because it allows for faster cooling and shorter cycle times.

7) A feature in a mold that allows a hollow, cylindrical part to be made is called a core. The core creates the internal cavity of the part while the mold cavity forms the external shape.

8) A vent in the mold is a narrow gap or channel that allows for the escape of air, gases, or excess material during the injection molding process. It helps to prevent issues such as air trapping, burn marks, and incomplete filling of the mold cavity.
