Two men are carrying a uniform beam of mass 200 kg of length 10 m on their shoulders. If one man is at 1 m from one end and other is 2 m from other end, find the load supported by each.

Two men A and B support the ends of a uniform beam 2 m long and weighing 50 kg. A weight of 50 kg hangs from the beam from a point 0.5 m from A. Assuming the bar is horizontal, the load shared by each man is

A uniform wooden plank, 5 m long and mass of 40 kg, is resting horizontally on two supports 0.5 m from each end. A boy weighing 45 kg stands on the plank, 1.5 m from one end. Find the reaction at the supports.

Two bodies of masses m and 2m are kept at distance r apart from each other. Then the value of G varies as

Solve the following examples: Ajit carries a load of 17 kg from the ground to the height of 2 m from the ground. Calculate the work done by him.

A string of mass 2.5 kg is under a tension of 200 N The length of the stretched string is 20 m. If the transverse jerk is struck at one end of the string, the disturbance will reach the other end in

Two boys are sitting very close to each other at a distance of 0.5 m from each other.If the mass of one boy is 40 kg and other is 50 kg,find the fravitational force between them.

A 2 m long wooden plank of mass 20 kg is pivoted (supported from below) at 0.5 m from either end. A person of mass 40 kg starts walking from one of these pivots to the farther end. How far can the person walk before the plank topples?

A ladder of length 17m rests with one end agianst a vertical wall and the other on the ground. If the lower end slips away at the rate of 1ms^(-1) , then when it is 8m away from the wall, its upper end is coming down at the rate of: a) 5/8 m/s b) 8/15 m/s c) (5pi)/8 m/s d) 8/5 m/s
