What is the average force F with which a drop hammer of weight W that falls through a distance h strikes the work, if it compresses it by amount d.
F= Wh/d : where h and d are the units of measurement
W=500 lbs
h= 4 feet=48 inches
d= compression of struck material (lets assume .25 inches)
F=500*48/.25=96000 pounds
