Answer:
claw hammer used to pull nails is a first class lever that places the load near the fulcrum to make it easier to move. You position the nail (load) near the head of the hammer (fulcrum) and push at the end of the long handle (effort). ... A class 3 lever has the effort between the fulcrum and the load.
