Pulley Practice

A pulley is a simple machine that consists of a wheel on an axle or shaft designed to support movement and change the direction of force applied to a rope or cable.

The main parts of a pulley include the wheel, axle, groove, and rope.

The wheel allows the rope to move smoothly and helps in changing the direction of the force applied.

The rope transmits the force applied to lift or move an object.

The ideal mechanical advantage of a pulley is the ratio of the load force to the effort force, indicating how much the pulley system multiplies the input force.

The ideal mechanical advantage of a single fixed pulley is 1.

The ideal mechanical advantage of a movable pulley is 2.

A compound pulley system combines fixed and movable pulleys to increase the mechanical advantage.

A fixed pulley is attached to a structure and does not move with the load, while a movable pulley moves with the load, providing greater mechanical advantage.

No, a ladder is not a pulley system; it is a simple tool used for climbing.
