Pile Driver with Nails (1M10.20)

Description:

Five nails are just barely driven into a piece of wood. Masses slide down a rod and strike the heads of the nails one by one, driving them into the wood. The penetration depths of the nails are compared as an indicator of the energy released in four different configurations (two different heights and two masses) versus the control nail. Note: See also Pile Driver with Foam (1N10.30).

Procedure or Operation Notes:

There are four combinations of the two masses (M) and two drop heights (H):

With the first nail as a control, the next four nails (from left to right) are: 1M from 1H, 2M from 1H, 1M from 2H, and 2M from 2H.
