Emmalie Berkovsky, Third Class Lever, taken at about 9:10 pm on Sept. 5

I took this in my apartment. This is one of my favorite third class levers (when it is hitting a nail), the ever-useful hammer. My hand acts as the fulcrum, the effort is in the middle of the hammer, and the load is the nail I hit.

Caleb Cheung's Lever (Nail Clipper)

A nail clipper has two classes of levers. The second class lever is located on the handle and the third class lever is located on the tweezers/ clipping part of the nail clipper. This picture was taken at my home in Missouri City, Texas.
