Answer:Yes,266.66 MPa
Explanation:
Given
Yield stress of material =140 MPa
Cross-section of 
Force(F)=8 MN
Therefore stress due to this Force(
)



Since induced stress is greater than Yield stress therefore Plastic deformation occurs
Answer:
Explanation:
Work, U, is equal to the force times the distance:
U = F · r
Force needed to lift the weight, is equal to the weight: F = W = m · g
so:
U = m · g · r
= 20.4kg · 9.81
· 1.50m
= 35.316 
= 35.316 W
Answer: (a) 36.18mm
(b) 23.52
