A wagon weighing 25 kN and moving at 4 km/hour is to be stopped at the bufferstop. Compute the number of close-coiled springs that would be required in the buffer stop to absorb the energy of motion during a compression of 250 mm. Each spring has 20 coils, made of 20 mm wire, the mean diameter of the coils being 200 mm. Take G=0.84 10N/mm.
