A rod of length 1m and mass `0.5 kg` is fixed at one end is initially hanging vertical. The other end is now raised until it makes an angle `60^(@)` with the vertical. How much work is required ?

A rod of length 1.0 m and mass 0.5 kg fixed at ond is initially hanging vertical. The other end is now raised until it makes an angle 60^@ with the vertical. How much work is required?

A rod of length 2 m and mass 0.5 kg is fixed at one end and allowed to hang vertically from a rigid support. Find the work done in raising the other end of the rod until it makes an angle of 60^(@) with the vertical. (g=10 ms^(-2))

A uniform rod of mass M & length L is hinged about its one end as shown. Initially it is held vartical and then allowed to rotate, the angular velocity of rod when it makes an angle of 37^(@) with the vertical is
