Answer:

4.25

Explanation:

The mean deviation is how far, on average, all values are from the middle. To do that, we subtract each element from the mean of the elements, take their absolute values, and then divide by the number of elements in the set. Here's the formula: $\sum\frac{|x-\mu|}{n}$

Here the mean is 9.5, the count n = 8, so the mean deviation is 4.25

Technician A is wrong.

Usually, hoods have what is called "Crush Zones" underneath the panels. The function of the Crush Zone is to prevent the hoods, during a collision, from entering into the passenger space.

The crush zones allow the hoods to fold instead.

Technician B is right.

Automobile producers now make use of a hybrid form of hood that consists of fiberglass reinforced with plastic.

They are mostly used for trucks that have a low volume of production.

The hood is built using a process called Resin Transfer Model (RTM).

Answer:

Gc(s) = $\frac{0.1s + 0.28727}{s}$

Explanation:

comparing the standard approximation with the plot attached we can tune the PI gains so that the desired response is obtained. this is because the time requirement of the setting is met while the %OS requirement is not achieved instead a 12% OS is seen from the plot.

attached is the detailed solution and the plot in Matlab
