A uniform L-shaped rod of mass 2m and length 2L, hangs from a hinge as shown (AO is horizontal and OB is vertical). If it is released from the position shown, then find the maximum angular velocity acquired by the end.

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 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 rod of mass m and length l is hinged at 'its' end and released from rest in position shown. Find the force exerted by the hinge when the rod becomes horizontal

A rod of mass m and length l is himged about one of its ends. The rod is released from horizontal position. When the rod becomes vertical, calculate (i) angular speed of the rod (ii) Hinge reaction.

A uniform slender bar B of mass m and length L supported by a firctionless m and length L supported by a firctionless pivot at A is released from rest at its vertical position as shown the figure. Calculate the reaction at pivot when the bar just acquires the horizontal position shown dotted.

A uniform rod of mass m and length L is free to rotate in the vertical plane about a horizontal axis passing through its end. The rod initially in horizontal position is released. The initial angular acceleration of the rod 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
