A sphere of mass 20 kg is suspended by a metal wire of unstretched length 4 m and diameter 1 mm. When in equilibrium there is a clear gap of 2 mm between the sphere and the floor. The sphere is gently pushed aside so that the wire makes an angle `theta` with the vertical and is released. Find the maximum value of `theta` so that the metal of the wire is `2.0xx10^11 Nm^-2`. Make appropriate approximation.
