Claw Hammer Physics: How Leverage Makes Nail Removal Easier #161455 (License: Personal Use)

This technical illustration demonstrates the principle of leverage in a claw hammer: applying force P at the end of the handle creates a larger force F at the claw tip, enabling easy nail extraction. Key variables include the effort arm length D (from fulcrum to handle grip), load arm d (from fulcrum to nail), and resisting force W (nail’s resistance). The ratio D/d determines the mechanical advantage.
