Question

A constant horizontal force f is apploed to the end b of the rod.Find the hinge reaction when the rod has turned by 90 degree

Answer 1

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 is released from rest in the position shown by slightly displacing it clockwise. Find the hinge reaction at the axis of rotation at the instant the rod turns through (a) 90* (b) 180*
