Answer:
Patterns may cloud the vision of the design process and send the engineer off track.
Explanation:
Engineers use a cyclical process and must stay on track during this process. A key point to an engineer is being able to have the ability to use creative and critical thinking.
To solve this problem, we must simply use the concept of Total Energy transferred both in terms of work and heat. This is basically conjugated in the first law of thermodynamics.
If we take the heat absorbed as positive and the expelled as negative we have that the total work done in the heat engine is


For the case of the engine pumps the Energy absorbed is

In this way the ratio between the two would be

So it is reversible, because the state of efficiency of the body is totally efficient.
A.
It would be released without a doubt so be careful!
Hope this helps :)
Answer:
a) 70.29 %
b) 37%
Explanation:
percent reduction can be found from:
PR = 100*(π(do/2)^2-π(df/2)^2)/π(do/2)^2
= 100*(π(11.34/2)^2-π(6.21/2)^2)/π(11.34/2)^2
=70.29 %
percent elongation can be found from:
EL =L_f - Lo/Lo*100
= (73.17 -53.3/53.3)*100
= 37%
