A sphere of radius 0.1 m and mass 8 π kg is attached to the lower end of a steel wire of length 5.0 m and diameter 10^−3. The wire is suspended from 5.22 m high ceiling of a room . When the sphere is made to swing as a simple pendulum, it just grazes the floor at its lowest point. Calculate the velocity of the sphere at the lowest position .

A very stiff bar (AB) of negligible mass is suspended horizontally by two vertical rods as shown in figure. Length of the bar is 2.5 L. The steel rod has length L and cross sectional radius of r and the brass rod has length 2L and cross sectional radius of 2r . A vertically downward force F is applied to the bar at a distance x from the steel rod and the bar remains horizontal. Find the value of x if it is given that ratio of Young’s modulus of steel and brass is Ys/YB = 2.
