Q2. A wooden pile that weighs 500 lb is driven into the ground by successive blows of a hammer weighing 1000lb that falls freely through a distance of 6ft upon the head of the pile. The average resistance to penetration is 4000 lb. How far does a single blow of the hammer drive the pile into the ground? Assume that the hammer and pile cling together after impact.

Question
Q2. A wooden pile that weighs 500 lb is driven into the ground by successive blows of a hammer
weighing 1000lb that falls freely through a distance of 6ft upon the head of the pile. The average
resistance to penetration is 4000 lb. How far does a single blow of the hammer drive the pile into the
ground? Assume that the hammer and pile cling together after impact.
Q3. A 1200-lb hammer falling freely through 3 ft drives a 600lb pile in. vertically into the ground.
Assuming the hammer and pile cling together after impact, determine the average resistance to
penetration of the pile
