Effective length of a pendulum is 50 cm and the mass of the bob is 4g . The bob is drawn to one side until the string is horizontal , and is then released. When the string makes an angle 60^@ with the vertical , what is the velocity and the kinetic energy of the bob ?

One end of a light string is fixed to the celling and the other end is tied to the wall. A body of mass 500 g is suspended from that string in such a way that the part of the string towards the wall remains horizontal and the portion towards the ceiling makes an angle of 30^(@) with the ceiling. Find the tension on the two parts of the string.

A copper wire of negligible mass of length 1 m and cross sectional area 10^-6 m^2 is kept on a smooth horizontal table with one end fixed. A ball of mass 1 kg is attached to the other end. The wire and the ball are revolving with an angular velocity of 20 rad.s^-1 . IF the elongation in the length of the wire is 10^-3m , obtain the Young's modulus. IF on increasing the angular velocity to 100 rad .s^-1 the wire breaks down, obtain the breaking stress.
