A uniform symmetric cross-section cantilever beam of length L is subjected to a transverse force P at the free end, as shown in the figure. The Young's modulus of the material is E and the moment of inertia is I. Ignoring the contributions due to transverse shear, the strain energy stored in the beam is
A
P2L3/(6EI)
B
PL3/(3EI)
C
P2L3/(3EI)
D
PL3/(6EI)

Correct : a
