In this episode you will learn: - Master the three classes of levers using the 'FLE 123' mnemonic to quickly identify the fulcrum, load, and effort arrangement. - Understand that the Ideal Mechanical Advantage (IMA) of a pulley system is found by counting only the rope segments directly supporting the load. - Recognize that a single fixed pulley only changes the direction of force, while a movable pulley multiplies force. - Apply the principle of torque (Force x Distance) to solve lever problems, knowing that greater distance from the fulcrum requires less effort. - Remember the force-distance trade-off: a higher mechanical advantage reduces the required force but increases the distance you must pull a rope or move a lever.
