Your task is to take the below code, and insert comments (using the “%” symbol) next to each line of code to make sure that you know what every line does.

NMax = 100;
partialSum = 0;
exactAnswer = pi^2;

for k=1:NMax
partialSum = partialSum + 6/k^2;
percentDiff(k) = abs(partialSum - exactAnswer)/exactAnswer*100;
end

NVector = [1:NMax];
plot(NVector,percentDiff);
xlabel('{{Noob}}');
ylabel('% Difference');

what does it imply if the efficiency of an engine is less than its corresponding carnot efficiency?.Describe two real life effects that might cause this difference.

1) Successful product development requires decision making in an environment free from constant change. TRUE or FALSE

2) One of the most difficult aspects of product development is recognizing, understanding and managing trade-offs. TRUE or FALSE

3) The cost of product development is roughly proportional to the number of people involved and the duration of the development project. TRUE or FALSE

4) Developing a successful product of even modest complexity requires hundreds, even thousands of decisions. TRUE or FALSE

5) Characteristics of dysfunctional product development teams include lack of empowerment, functional allegiances transcending project goals and inadequate resources. TRUE or FALSE

A pressure vessel is being designed to hold compressed methane to fuel a liquid rocket motor at a maximum pressure of 50 bar. If the methane is to be stored at 40 bar, -18 C, determine the mass contained in a 10 m3 tank using the following assumptions:

a) The ideal gas equation of state.

b) The van der Waals equation of state.

c) Using CoolProp. Comment on the accuracy of each.

Air with a dry bulb temperature 75 F and a wet bulb temperature 65 F is at a sea level pressure of 14.7 psia. Using equations to calculate (a) humidity ratio, (b) the relative humidity of the air, (c) enthalpy, (d) dew point, and (e) the mass density of the dry air. (50)

Write a program to run on your Arduino and PortMaster board that will sequentially turn on and off the LED segments, so it resembles Cylon eyes (https://youtu.be/UajcgzK2shQ). Use the millis() construct shown in lecture rather than delay(). The traverse from one side to the other should take about 1 second.

Five lbs of propane is contained in a closed, rigid tank initially at 80 lbf/in.², 50°F. Heat transfer occurs until the final temperature in the tank is 0°F. Kinetic and potential energy effects are negligible.

Determine the amount of energy transfer by heat, in Btu.

The drive shaft of a dump truck is constructed of 3.5” OD x 1/4” wall round tubing made of ASTM A242 steel. The driveshaft is 65” long and is subjected to 500 lbf*ft of torque.

• What is the maximum shear stress in the drive shaft?

• What is the safety factor with respect to yielding?

• How much torque would result in a 1° twist of the drive shaft?
