A uniform slender rod of mass `m` and length `L` is released from rest, with its lower end touching a frictionaless horizontal floor. At the initial moment, the rod is inclined at an angle `theta=30^(@)` with the vertical. Thent he value of normal reaction from the from the floor just after release will be

A uniform slender rod of mass m and length L is released from rest, with its lower end touching a frictionaless horizontal floor. At the initial moment, the rod is inclined at an angle θ=30∘ with the vertical. Thent he value of normal reaction from the from the floor just after release will be 4mg /7 In the above problem, the initial acceleration of the lower end of the rod will be

A rod of mass m and length l is held vertically on a smooth horizontal floor. Now it is released from this position, find the speed of its centre of mass when it makes an angle theta with the vertical.

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 uniform chain of mass M and length L is held verticallyi in such a way that its lower end just touches the horizontal floor. The chain is released from rest in this position. Any portion that strikes the floor comes to rest. Assuming that the chain does not form a heap on the floor, calculate the force exerted by it on the floor when a length x has reached the floor.
