Question

One end of a uniform rod of length 21 and mass m rests against a smooth
horizontal floor and the other against a smooth vertical surface.
Assuming that the rod is constrained to move under gravity with its ends
always in contact with the surfaces, use the Hamilton-Jacobi equations to
reduce the solution of the problem of quadratures.​

Answer 1

Answer:

The force exerted by the hinge on the rod is centripetal force and is given by:

F=mrω

2

⟹F=mlω
