2. ### A uniform rod allowed to rotate about an axis and then it breaks

A uniform rod AB of length ℓ is free to rotate about a horizontal axis passing through A. The rod is released from rest from the horizontal position. If the rod gets broken at midpoint C when it becomes vertical, then just after breaking of the rod. Choose multiple answeres from the below...

28. ### A problem on rotation

1. Homework Statement A horizontal platform rotates around a vertical axis at angular velocity ω. A disk with radius R can freely rotate and move up and down along a slippery vertical axle situated at distance d > R from the platform’s axis. The disk is pressed against the rotating platform due...
29. ### Maximum torque on a rotating cylinder kept on a moving plank

1. Homework Statement A cylinder of mass M and radius R is resting on a horizontal platform (which is parallel to the x-y plane) with its axis along the y- axis and free to rotate about its axis. The platform is given a motion in the x-direction given by x= Acos(ωt). There is no slipping...
30. ### An equilibrium problem -- Spinning a hinged rod and a ball

1. Homework Statement This is a practice olympiad problem A light rod with length l is hinged in such a way that the hinge folds in one plane only. The hinge is spun with angular speed ω around a vertical axis. A small ball is fixed to the other end of the rod. (a) Find the angular speeds for...
