A sphere of radius 0 1m and mass 8 kg is attached to the lower end of a steel wire of length 5m and diameter 10 m The wire is suspended from 5 22m high ceiling of the room When the sphere is made to swing as a simple pendulum it just grazes the floor at its lowest point The velocity of the sphere at the lowest position is m s Y for steel 1 994 10 N m A steel wire of diameter 0 8 mm and length 1m is clamped firmly at two points A and B which are 1m apart and in the same plane A body is hung from the middle point of the wire such that the middle point sags 1 cm lower from the original position The mass of the body is gm Young s modulus of the material of wire is 2 10 N m
