Homework Statement
A uniform elastic plank moves due to a constant force F distributed uniformly over the end face. The area of the ned face is S and Young's modulus = E . What is the average strain produced in the direction of force ?
Homework Equations
E*strain=stress...
The Attempt at a Solution
I am not getting any clue...how can stress or strain develop unless equal and opposite forces are acting? How ro approach this sum?
