A Steel pile is driven a distance (d) into the ground by a hammer of mass (M) 450kg, dropped from a height (h) of 3.25m above the top of the pile. The mass of the pile (m) is 40kg and the average resistance of the ground to penetration (Fr) is 45kN.
b. The velocity and kinetic energy of the hammer-pile combination immediately after impact.© BrainMass Inc. brainmass.com February 24, 2021, 2:31 pm ad1c9bdddf
This shows how to calculate velocity and kinetic energy with a given situation.
