Question

3/263 The 3000-kg anvil A of the drop forge is mounted on a nest of heavy coil springs having a combined stiffness of 2.8(10º) N/m. The 600-kg hammer B falls 500 mm from rest and strikes the anvil,which suffers a maximum downward deflection of24 mm from its equilibrium position. Determine the height h of rebound of the hammer and the coefficient of restitution e which applies.
