What is a lever? A simple machine that provides a mechanical advantage in carrying loads. Composed of a fulcrum (or pivot) and rigid rod (or beam). What is the formula for calculating the load or the effort of a lever? W1 x L1 = W2 x L2 (Weight of the load x distance of the load from the fulcrum = weight of the effort x distance from the fulcrum to the effort.) What is a first class lever? A lever where the fulcrum is located between the force and the load. ie. seesaw Wha...
