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.
