Solution:

QUESTION: 2

Which one of the following gives the correct expression for strain energy stored in a beam of length L and of uniform cross-section having moment of inertia I and subjected to constant bending moment M?

Solution:

QUESTION: 3

A square bar of side 40 mm and length 1 m is subjected to an axial load P. The same bar is then used as a cantilever beam and subjected to an end load P. The ratio of the strain energies, stored in the bar in the second case to that stored in the first case, is

Solution:
