physics

In one of my demonstrations, I let someone break concrete blocks that are placed on top of me while I am sandwiched between two beds of nails. (See the pictures.) Using your knowledge on Newton’s laws, explain how the nails do not penetrate into my body. All discussions should include an in depth analysis and references.

2. Discuss the function of a washing machine/dryer in terms of circular motions, centripetal force, and pseudo centrifugal force. Elaborate on the separation process of water from the wet cloths using physics knowledge.
