Pulley Practice

Front

What is a pulley?

Back

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 load.

Front

What is mechanical advantage in a pulley system?

Back

Mechanical advantage is the ratio of the load force to the effort force in a pulley system, indicating how much the machine amplifies the input force.

Front

How do you calculate the distance you need to pull the rope in a pulley system?

Back

To calculate the distance you need to pull the rope, multiply the distance you want to lift the load by the mechanical advantage of the pulley system.

Front

What is the ideal mechanical advantage of a fixed pulley?

Back

The ideal mechanical advantage of a fixed pulley is 1, as it does not change the amount of force needed to lift the load.

Front

What is the term used for the object being moved by a machine?

Back

The term used for the object being moved by a machine is 'load'.

Front

What is a fixed pulley?

Back

A fixed pulley is a type of pulley that is anchored in place and does not move with the load, allowing the user to change the direction of the force applied.

Front

What is a movable pulley?

Back

A movable pulley is a type of pulley that moves with the load, providing a mechanical advantage by reducing the amount of effort needed to lift the load.

Front

What is the purpose of an axle in a pulley system?

Back

The axle in a pulley system serves as the central shaft around which the wheel rotates, allowing for smooth movement and force transmission.

Front

How does a compound pulley system work?

Back

A compound pulley system combines fixed and movable pulleys to increase mechanical advantage, allowing for easier lifting of heavy loads.

Front

What is the formula for calculating mechanical advantage in a pulley system?

Back

The formula for calculating mechanical advantage in a pulley system is: Mechanical Advantage = Load Force / Effort Force.
