Answer:
W = 166.35 KJ
Explanation:
P₁ = 600 KPa
V₁ = 0.4 m³
V₂ = 0.2 m³
T = 300 K
W = ?
We can find the solution from the standard relation for work in an isothermal process
W = -n*R*T*Ln (Vf / Vi)
We know that
n*R*T = P*V ⇒ P₁*V₁ = P₂*V₂ = n*R*T = 600 *0.4 = 240
Now, we use the equation
W = -n*R*T*Ln (Vf / Vi) = - P₁*V₁*Ln (Vf / Vi)
⇒ W = -240*Ln (0.2 / 0.4) = 166.35 KJ

Answer:
D.
cutting-plane view
Explanation:
When using the cutting plane view, cutting plane lines are utilized to show a plane or planes in which a sectional view is shown. Section views give a clear indication of interior views of an object or structure including hidden parts or features which are not directly visible through convectional ways such as direct observation.
Answer:
The biggest expectation of an engineer when he tests out a new design is that he expects the product to not fail, and all the stress and strains does not exceed the failure criteria.
Explanation:
In engineering design, failure of materials is considered, and the designed is usually designed to not reach or exceed the failure region of its stress strain relationship. This is why factor of safety is usually determined for each material, and it serves as a guideline for the designing of new designs. This factor of safety is the value, below which the material properties is able to cope with design stress and strain, and above which failure is likely to occur.
