Question 5

What is the expression for the strain energy due to bending of a cantilever beam (length L, modulus of elasticity E and moment of inertia I?)

Question 6

A helical compression spring of stiffness K is cut into two pieces, each having equal number of turns and kept side-by-side under compression. The equivalent spring stiffness of this new arrangement is equal to
