Solution Preview

By energy law,
Initial mechanical energy = final mechanical energy
Initial energy
= potential enrgy of spring (PESi)
+ gravitational potential energy of rod (PERi) (reference is B)

Final energy
= potential energy of spring(PESf)
+ rotational kinetic energy of rod (RKERf)

Because, natural length of spring,
lo = 225 mm
initial length of spring,
li = ...
