Answer:
W=-940.36 KJ
Explanation:
Given that

Process follows pv=constant
So this is the isothermal process and work in isothermal process given as

Now by putting the values (1.4 bar =140 KPa)


W=-940.36 KJ
Negative sign indicates that this is a compression process and work will given to the system.
Answer:
Stress-concentration
In the machine component the stress become concentrate at the point a particular point and due to this crack formation takes places and after some time some the machine component become fails.High stress concentration means high stress at that point.
It is very important in the design point of view because we have to find out where stress concentration is high and needs to take proper factor of safety to avoid the failure of the machine component.Generally at sharp corner,sudden change and complex shapes stress concentration is high.
I don’t know if I’m right but I’m guessing B
Answer:
I believe it is a civil drafter

Answer:
The explanations are provided below.
Explanation:
a) The accelerated thermal cycling test is a test that is performed to evaluate the fatigue strength of electronic solder connections. The glass transition temperature given as
is a frequently used parameter to test the degree of cure of an epoxy encapsulant.
b) The Coefficient of Thermal Expansion of Encapsulant
This is an important parameter to prevent crackling. Crackling occurs when a joint is subjcted to high temperatures during reflow soldering. Thus, the property is important in determining the limits of the joint.
