Pendulum Hammer Impact Force Calculation | Physics Forums

If you try this stunt, be it known that we, the Science Guys, did not encourage you to do so. Most children know of someone who has stepped on a nail and sustained a serious puncture wound. We naturally think of nails as being able to pierce the skin. How can someone lying on a bed of nails not have hundreds of holes in their skin? Actually, this is a timely question because we happen to have constructed a bed of nails at Union last month. The pressure on the skin determines whether or not a nail pierces the skin.

If the hammer is swung by hand through an arc, it is not obvious to me how to measure the speed the hammer will be when it strikes the metal. Also, when the hammer strikes the metal, the heavier it is, the more force there will be persistent and the less rebound. Also, the smith may use what is called a "dead blow" hammer to reduce the rebound. Thus, measuring the force is not just a question of the instantaneous force of the hammer, but how much it "presses" after that first instant, its impetus so to speak.
