A rod of length l and mass m is hinged at A. It is released from horizontal position from rest. When it comes to position AB, and makes and angle of `30^(@)` with vertical Then the angular velocity in this position is given as `((N sqrt(3)g)/(2l))^(1/2)`.Find N:

One end of a uniform rod of length l and mass m is hinged at A. It is released from the rest from horizontal position AB as shown in figure. The force exerted by the rod on the hinge when it becomes verticle is

A uniform thin rod of length l and mass m is hinged at a distance l//4 from one of the end and released from horizontal position as shown in Fig. The angular velocity of the rod as it passes the vertical position is

A uniform rod of mass m, hinged at its upper end, is released from rest from a horizontal position. When it passes through the vertical position, the force on the hinge is

A rod of length L is hinged from one end. It is brought to a horizontal position and released. The angular velocity of the rod, when it is in vertical position, is

A rigid rod of mass m & length l is pivoted at one of its ends. If it is released from its horizontal position, find the speed of the centre of mass of the rod when it becomes vertical.

A bob hangs from a rigid support by an inextensible string of length l. It is released from rest when string makes an agngle 60^(@) with vertical . The speed of the bob at the lowest position is

A rod of mass M and length L is made to stand vertically. Potential energy of the rod in this position is

A rod of length 10 meter has one end on smooth floor and the other end on smooth wall is released from the rest the position shown in figure. When the rod makes an angle of 37^(@) with the horizontal, answer the following: The velocity of centre of mass of rod is :

A rod of length L is hinged from one end. It is brought to the horizontal position and released. The angular velocity of the rod when it is in the vertical position is sqrt(Kg//L) . Then find the value of K.

A uniform rod AB of length l and mass m is free to rotate about point A. The rod is released from rest in the horizontal position. Given that the moment of inertia of the rod about A is (ml^ 2 ) / ( 3 ) , the initial angular acceleration of the rod will be
