A cylinder of relative density 0.7 is 0.5 m high and the radius of its base is 1m . It floats in water with its axis vertical . Find the legth of the cylinder inside water. What force is needed to raise it by 1 cm ? Denstiny of water =1000 kg m^(-3)

A uniform rod of mass M and length L is hinged at its end. The rod is released from its vertical position by slightly pushing it. What is the reaction at the hinge when the rod becomes horizontal, again vertical.

A rod of mass m and length l is held vertically on a smooth horizontal floor. Now it is released from this position, find the speed of its centre of mass when it makes an angle theta with the vertical.
