A uniform rod of mass M and length L is hinged at one end and then released from horizontal position. The hinge force when the rod becomes vertical is (A)3.5 Mg (B)2Mg (C)3Mg (D)2.5Mg

A simple pendulum A and a homogeneous rod B hinged at its enda are released from horizontal position as shown in figure.

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 thin uniform rod mass M and length L is hinged at its upper end. And released from rest from a horizontal position. The tenstion at a point located at a distance L//3 from the hinge point, when the rod become vertical will

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 uniform rod of length 75 cm is hinged at one of its ends and is free to rotate in vertical plane. It is released from rest when rod is horizontal. When the rod becomes vertical, it is breaks at mid - point and lower part now moves freely. The distance of centre of lower part from hinge, when it again becomes vertical for the first time is r . Find the approximate value of 2r .

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

Two particles each of mass m are attached at end points of a massless rod AB of length l. Rod is hinged at point C as shown. Rod is released from rest from horizontal position. At the instant when rod reaches its vertical position as shown, which of the following is / are correct:

A uniform rod of mass m and length L is hinged at one end and free to rotate in the horizontal plane. All the surface are smooth. A particle of same mass m collides with the rod with a speed V_(0) . The coefficient of restitution for the collision is e=(1)/(2) . If hinge reaction during the collision is zero then the value of x is :

A uniform rod of mass m and length L is hinged about one end and can freely rotate in a vertical plane. The angular velocity of the rod, when it falls from position P to Q. through an angle alpha starting from rest, 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
