Two different single acting hammers are being considered for an open- ended pipe pile. Hammer A has a ram weight of 30 kN and a stroke of 3 m. Hammer B has a ram weight of 15 kN and stroke of 5 m. Both hammers use similar appurtenances. Which hammer will deliver the most energy to the pile? Which hammer will generate the highest stresses in the pile?
