Answer:

The acceleration of the car is +10 m/s^2.

Explanation:

Using the formula S = ut + 1/2at^2, we can calculate the acceleration of the car.

When the car covers 450 m in 5 seconds, we have:

450 = 5u + 1/2 x a x 5^2

Simplifying this equation gives us:

450 = 5u + 12.5a

Next, when the car covers a total distance of 1150 m in 15 seconds, we have:

1150 = 10u + 1/2 x a x 10^2

Simplifying this equation gives us:

1150 = 10u + 50a

We can now solve for u in terms of a using the first equation:

5u = 450 - 12.5a

u = (450 - 12.5a)/5

Substituting this expression for u into the second equation gives:

1150 = 2(450 - 12.5a) + 50a

Simplifying and solving for a gives:

a = 10 m/s^2

Therefore, the acceleration of the car is +10 m/s^2.

The concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

To determine the concentration ratio and length of the parabolic surface for a Parabolic Trough Collector (PTC) with the given parameters, we can use the following formulas:

Concentration Ratio (CR) = Rim Angle / Aperture Angle

Length of Parabolic Surface (L) = Aperture^{2} / (16 * Focal Length)

First, let's calculate the concentration ratio:

Given:

Rim Angle (θ) = 80º

Aperture Angle (α) = 5.2 m

Concentration Ratio (CR) = 80º / 5.2 m

Converting the rim angle from degrees to radians:

θ_rad = 80º * (π / 180º)

CR = θ_rad / α

Next, let's calculate the length of the parabolic surface:

Given:

Aperture (A) = 5.2 m

Receiver Diameter (D) = 50 mm = 0.05 m

Focal Length (F) = A^{2} / (16 * D)

L = A^{2} / (16 * F)

Now we can substitute the given values into the formulas:

CR =\((80º * (π / 180º)) / 5.2 m\)

L = \((5.2 m)^2 / (16 * (5.2 m)^2 / (16 * 0.05 m))\)

Simplifying the equations:

CR ≈ 1.48

L ≈ 5.2 m

Therefore, the concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

The displacement of end D with respect to end A is 6.04 micrometers, if assembly is made of 6061-T6 aluminum.

To calculate the displacement we can use the formula for the deformation of a bar under axial load:

δ = P L / (A E)

where delta is the deformation (displacement) of the bar,

P is the axial load applied to the bar,

L is the length of the bar,

A is the cross-sectional area of the bar, and

E is the modulus of elasticity of the material.

For segment AB, the axial load is given by:

P = F = (2/3) W = (2/3) (9.81 m/s²) (4 kg) = 26.16 N

The length and cross-sectional area of segment AB are:

L = b = 455 mm = 0.455 m

A = (pi/4) d² = (pi/4) (20 mm)² = 314.16 mm² = 0.00031416 m²

The modulus of elasticity of 6061-T6 aluminum is given as E = 68.9 GPa = 68.9 x 10⁹ Pa.

Therefore, the deformation of segment AB is:

δ_{AB} = P L / (A E)

= (26.16 N) (0.455 m) / (0.00031416 m²) (68.9 x 10⁹ Pa)

= 1.83 x 10⁻⁶ m = 1.83 micrometers.

For segment BC, we can assume that there is no deformation since it is a tube and is not subject to axial load.

For segment CD, the axial load is given by:

P = F = (1/3) W = (1/3) (9.81 m/s²) (4 kg) = 13.88 N

The length and cross-sectional area of segment CD are:

L = b = 455 mm = 0.455 m

A = (pi/4) d² = (pi/4) (30 mm)² = 706.86 mm² = 0.00070686 m²

Therefore, the deformation of segment CD is:

δ_{CD} = P L / (A E) = (13.88 N) (0.455 m) / (0.00070686 m²) (68.9 x 10⁹ Pa)

= 4.21 x 10⁻⁶ m = 4.21 micrometers.

To find the displacement of end D with respect to end A, we can sum up the deformations of segments AB and CD, since they are in series:

δ_{D} = δ_{AB} + δ_{CD}

= (1.83 + 4.21) x 10⁻⁶ m = 6.04 micrometers

Therefore, the displacement of end D with respect to end A is 6.04 micrometers.

Section Key Terms

kinetic friction static friction

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 volume of the artificial reservoir can be calculated using the formula: Volume = Area x Depth. First, we need to convert the area of 50 acres to square meters. One acre is equal to 4046.86 square meters, so 50 acres is equal to:
50 acres x 4046.86 square meters/acre = 202343 square meters.

To calculate the volume of an object, we need to know its dimensions. In this case, we were given the area (50 acres) and the depth (7 feet) of the artificial reservoir. We used the formula Volume = Area x Depth to find the volume in cubic feet. However, since the final answer is required in cubic meters, we needed to convert the feet to meters using the conversion factor 0.3048 meters/foot.

To calculate the volume of the reservoir, we need to convert the area and depth into meters, then multiply them together.

Convert the area from acres to square meters.
1 acre = 4,046.86 square meters
50 acres = 50 * 4,046.86 = 202,343 square meters
Convert the depth from feet to meters.
1 foot = 0.3048 meters
7 feet = 7 * 0.3048 = 2.1336 meters
Calculate the volume.

Given Data:

Internal pressure of tank = 90 psi

Internal diameter of tank = 22 in

Wall thickness = 0.25 in

Stress components are to be determined at point A and maximum shear is to be calculated.

Volume Element:

The volume element at point A has six faces and the stress components are acting on these faces. The stress components acting at point A need to be calculated.

Stress Components:

Consider the cylinder element shown below:

The stress acting on the horizontal and vertical faces is called longitudinal stress and the stress acting on the oblique faces is called shear stress.

Longitudinal Stress:

Longitudinal stress is given by the formula:

σL = (P x D) / (4t)

Where,

P is the internal pressure of the tank

D is the internal diameter of the tank

t is the thickness of the tank

Substituting the values in the formula, we get:

σL = (90 x 22) / (4 x 0.25)

σL = 1980 psi

Shear Stress:

The shear stress is given by the formula:

τ = σ / 2

Where,

σ is the longitudinal stress

Substituting the value of σ in the formula, we get:

τ = 1980 / 2

τ = 990 psi

The shear stress acting on the oblique faces is 990 psi and the maximum shear stress acting on the element is 990 psi. Hence, the maximum shear stress that this material would experience is 990 psi.
