1. Discuss how products incorporate aesthetic design and why this appeals to target markets 2. Discuss how the universal design process has impacted engineering design and the impact these expectations will have on the future of product design.
Explanation:
Remember, to say a product is incorporated with aesthetic design implies that its overall appearance is designed to look beautiful to the eyes of the user/buyer. For example, a clothing company whose target market is mainly focused on women's clothing would need to take into consideration that certain colors like pink, blue, etc are attractive to women more than men. So they'll have to ensure the colors of their clothing are suitable to the needs of their target market.
The Universal Design process involves building products that can be used by a wide range of users at ease. For example, you may ask yourself: Is my product/service easily accesible to those with disabilities?
Other processes include;
Defining who the users (or universe) are of the products. Involve consumers in the design.Follow the existing standards of product designEvaluate and review your universal design methodsFind the volume of the rectangular prism
9 cm
10 cm
Answer:
V= 90h cm³ where h is the height of the rectangular prism.
Explanation:
The formula for volume of a rectangular prism is ;
V=l*w*h where;
V=volume in cm³
l= length of prism=10cm
w =width of the prism = 9 cm
Assume the height of the prism as h cm then the volume will be;
V= 10* 9*h
V= 90h cm³
when the value of height of the prism is given, substitute that value with h to get the actual volume of the prism.

problem resulting from using a seat warmer for too long, it is called by ___
The problem resulting from using a seat warmer for too long is called "Toasted Skin Syndrome." In rare situations, the condition may cause skin cancer.
Toasted Skin Syndrome is also known as erythema ab igne. It is a condition that causes skin discoloration and pigmentation due to prolonged exposure to low heat. This condition is generally caused by extended periods of exposure to heat sources such as a laptop, heating pad, hot water bottle, or seat warmer. The heat source doesn't have to be too hot to cause this condition.
It takes long-term exposure to lower heat to create this problem. Toasted skin syndrome appears like a spotty or patchy reddish or brownish discoloration of the skin. It is most frequently seen on the thighs, arms, and legs, but it can occur anywhere on the body.
This is a non-cancerous condition that can go away on its own once the heat source has been removed. The affected skin may feel warm, itchy, or tender to the touch. Furthermore, Therefore, it is essential to take precautions to avoid prolonged exposure to heat sources.

a) When comparing the quality asphaltic material provided by two plants, X and Y, for a certain highway job, sufficient samples from each plant were taken and tested. The results from Plant X, showed a peaked bell shaped distribution (Lepto Kurtosis) while those from Plant Y gave a flat shape (Platy Kurtosis). Which plant, in your opinion, has a better quality control and why?
Based solely on the shape of the distribution of their test results, it is my opinion that Plant X has better quality control than Plant Y.
A peaked bell-shaped distribution, or Lepto Kurtosis, indicates that the data is clustered more towards the center of the distribution, with fewer extreme values. On the other hand, a flat shape, or Platy Kurtosis, suggests that the data is evenly distributed, with no significant clustering towards the center or extremes.
The peaked bell-shaped distribution of Plant X's results suggests that they have a tighter control over the consistency of their material. The fewer extreme values in the data indicate that Plant X is producing asphaltic material that meets the required specifications more consistently than Plant Y.

what are arrows shot from untuned bows likely to do?
Arrows shot from untuned bows are likely to have inconsistent and inaccurate flight paths.
When a bow is not properly tuned, it means that the various components of the bow (limbs, string, and arrow rest) are not working in harmony, leading to imprecise arrow release. Consequently, arrows shot from untuned bows may wobble, drift, or experience "porpoising" is up and down oscillation during flight. These irregularities can cause the arrow to miss the intended target or have unpredictable impact points. Therefore, it is crucial to tune a bow properly to ensure better arrow flight, improved accuracy, and overall enhanced shooting performance.

in the section discussing the precipitation of the tin subgroup, why does the addition of sulfuric acid cause the precipitation of the tin metal sulfides?
the addition of sulfuric acid can be used to enhance the precipitation of tin metal sulfides by increasing the concentration of tin ions available for reaction with hydrogen sulfide gas.
The precipitation of tin metal sulfides occurs when hydrogen sulfide gas is passed through a solution containing tin ions (Sn2+ or Sn4+), resulting in the formation of insoluble tin sulfides.
The addition of sulfuric acid can be used to enhance the precipitation of tin metal sulfides because it reacts with the tin ions in solution to form tin sulfate, which is more soluble in water than the tin ions themselves. This increased solubility allows more tin ions to be available for reaction with the hydrogen sulfide gas, resulting in more tin metal sulfides being formed.
The reaction between sulfuric acid and tin ions can be described as follows:
Sn2+ + H2SO4 -> SnSO4 + 2H+
The resulting tin sulfate (SnSO4) is more soluble in water than the tin ions, which increases the concentration of tin ions available for reaction with hydrogen sulfide:
Sn2+ + H2S -> SnS + 2H+
The insoluble tin sulfide (SnS) precipitates out of solution as a solid, which can be filtered and collected.
Therefore, the addition of sulfuric acid can be used to enhance the precipitation of tin metal sulfides by increasing the concentration of tin ions available for reaction with hydrogen sulfide gas.

true or false. marin factors reduce the strength and stress concentrations factors increase the stress; therefore, they both increase the safety factor.
The given statement is false because Marin factors do not reduce the strength and stress concentrations factors do not increase the stress. Instead, they both reduce the safety factor.
Marin factor is a corrosion factor that takes into account the corrosion of the material of interest. When compared to the yield strength of the material, corrosion usually reduces the yield strength of the material. Because of this, the engineering process must consider the effect of corrosion on the material being used to ensure that it does not become so degraded that it fails prematurely. Hence, the Marin factor increases the safety factor and hence reduces the likelihood of failure.
When there is a change in section or a flaw in a structural member, stress concentration occurs. This is where the stress concentration factor is used. It is used to assess the effect of these conditions on the stress levels that result. The stress concentration factor increases the maximum stress that results in the presence of stress raisers. As a result, it reduces the safety factor and makes it more likely that the structural member will fail prematurely, unlike the Marin factor.
Therefore, the statement is false because the Marin factor reduces the stress and the stress concentration factor increases the stress, and they both reduce the safety factor instead of increasing it.

Explanation:
technician a says that a missing wire harness grommet may cause wind noise. technician b says that dealer installed bug shields will not affect airflow around a vehicle. who is right?
Technician a says that a missing wire harness grommet may cause wind noise. technician b says that dealer installed bug shields will not affect airflow around a vehicle. Both technicians A and B are correct in their statements.
Technician A is right. Wind noise can be generated by airflows around the exterior of the vehicle, and a missing wire harness grommet might provide an air entry point. This indicates that air travels around the vehicle and can cause wind noise through an unsealed hole. It's also worth noting that a wire harness grommet isn't the only component that might produce wind noise.
Other items, such as an unsealed window, might create wind noise by allowing air into the vehicle. The grommet may not always produce the wind noise, but in most situations, it is the primary source of wind noise. Technician B is also right.
The bug shield is aerodynamically designed to fit on the hood of the vehicle and deflect insects, debris, and other objects from hitting the windshield. The shield's design will not obstruct the air's path or alter the vehicle's aerodynamics.

In an international film festival, a penal of 11 judges is formed to judge the best film. At
last two films FA and FB were considered to be the best where the opinion of judges got
divided. Six judges where in favor of FA whereas five in favor of FB. A random sample
of five judges was drawn from the panel. Find the probability that out of five judges,
three are in favor of film FA.Enunciate demerits of classical probability.
Answer:
International Film Festival
Judging the best best film:
a. The probability that out of five judges (random sample), three are in favor of film FA is:
= 33%.
b. The demerits of classical probability are:
1. Classical probability can only be used with events that have definite numbers of possible outcomes.
2. Classical probability can only handle events where each outcome is equally likely.
3. Classical probability is based on the assumption of linear relationship (which is not always true in real life) between the latent variable and observed scores.
Explanation:
a) Number of judges = 11
Number of judges in favor of FA film = 6
Number of judges in favor of FB film = 5
Probability of judges in favor of FA film = 6/11
Probability of judges in favor of FB film = 5/11
Random sample of judges = 5
Probability that out of five judges, three are in favor of film FA = 3/5 * 6/11
= 18/55
= 33%
b) Classical probability is the simple probability showing that each event has equal chance of happening. It can be contrasted with empirical probability that is obtained from experiments.

Use the following transfer functions to find the steady-state response y_ss(t) to the given input function f(t). a. T(s) = Y(s)/F(s) = 10/(10s + 1)(4s + 1), f(s) = 10 sin 0.2t . b. T(s) = Y(s)/F(s) = 1/2s^2 + 20s + 200, f(t) = 16 sin 5t
To find the steady-state response y_ss(t), we need to first take the Laplace transform of the input function f(t) and substitute it into the transfer function T(s).
Then, we can take the inverse Laplace transform of the resulting expression to obtain y(t), and finally take the limit as t approaches infinity to find the steady-state response y_ss(t).
a. T(s) = Y(s)/F(s) = 10/(10s + 1)(4s + 1), f(s) = 10 sin 0.2t
Taking the Laplace transform of f(t), we get:
F(s) = 10/(s^2 + 0.04)
Substituting F(s) into T(s), we get:
Y(s)/[10/(s^2 + 0.04)] = 10/(10s + 1)(4s + 1)
Y(s) = [10/(10s + 1)(4s + 1)] * 10/(s^2 + 0.04)
Simplifying the expression, we get:
Y(s) = 2/(2s + 1) - 2/(4s + 1) + 0.1/(s^2 + 0.04)
Taking the inverse Laplace transform, we get:
y(t) = 2e^(-t/2) - 2e^(-t/4) + 0.2sin(0.2t)
Taking the limit as t approaches infinity, we see that the first two terms decay to zero, leaving us with the steady-state response:
y_ss(t) = 0.2sin(0.2t)
b. T(s) = Y(s)/F(s) = 1/(2s^2 + 20s + 200), f(t) = 16 sin 5t
Taking the Laplace transform of f(t), we get:
F(s) = 16/(s^2 + 25)
Substituting F(s) into T(s), we get:
Y(s)/[16/(s^2 + 25)] = 1/(2s^2 + 20s + 200)
Y(s) = [1/(2s^2 + 20s + 200)] * 16/(s^2 + 25)
Simplifying the expression, we get:
Y(s) = (4s + 40)/(s^4 + 50s^2 + 625)
Taking the inverse Laplace transform, we get:
y(t) = 4cos(5t) + 4sin(5t)
Taking the limit as t approaches infinity, we see that both terms are periodic with period 2π/5, so the steady-state response is simply:
y_ss(t) = 4cos(5t) + 4sin(5t)

A continuous and aligned fiber-reinforced composite is manufactured using 80 vol% aramid fiber (a kevlar-like compound) embedded nylon 6-6. A part for a high-performance aircraft utilizes this composite. If the part experiences 953 lb-f (pounds force) along the fiber alignment axis, what is the force conveyed by the fibers ?
Answer:
the force conveyed by the fibers is 947.93 lb-f
Explanation:
Given the data in the question;
V_f = 80% = 0.8
V_m = 1 - V_f = 1 - 0.8 = 0.2
Now,
length of fibre L_f = length of Nylon L_n
V_f = A_f × L_f = 0.8
V_m = A_n × L_n = 0.2
so
V_f/V_m = A_f/A_n = 0.8/0.2
A_f/A_n = 4
now, the strains in fibre is equal to strains in nylon
(P/AE)f = (P/AE)n
P_f/A_fE_f = P_n/A_nE_n
P_f = (A_f/A_n)(E_f/E_n)(P_n)
P_f = ( 4 )( 131 / 2.8 )(Pn)
P_f = 187.14Pn
and P_n = Pf / 187.14
Hence
given that P_total = 953 lb-f
P_f + P_n = 953
P_f + ( P_f / 187.14 ) = 953
P_f( 1 + ( 1 / 187.14 ) ) = 953
P_f( 1.00534359 = 953
P_f = 953 / 1.00534359
P_f = 947.93 lb-f
Therefore, the force conveyed by the fibers is 947.93 lb-f
