Strength of Materials

A railway wagon weighing 200 kN is stopped by a buffer of 4 springs while moving at a speed of 10 km/hr. If the maximum compression of springs is 150 mm, find the diameter of the spring rod if the mean diameter of the spring coil is 200 mm and 8 number of turns are in a coil. Take modulus of rigidity = 80 GPa.
