IPC Pulleys, Wheel & Axle, & MA

Front

What is a pulley?

Back

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

Front

What is mechanical advantage (MA)?

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied to it.

Front

What is the formula for calculating mechanical advantage?

Back

Mechanical Advantage (MA) = Output Force / Input Force.

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.

Front

What is a moveable pulley?

Back

A moveable pulley is a type of pulley that moves with the load, providing a mechanical advantage.

Front

What is a wheel and axle?

Back

A wheel and axle is a simple machine consisting of a larger wheel attached to a smaller axle, allowing for the transfer of force.

Front

How does a wheel and axle provide mechanical advantage?

Back

A wheel and axle provides mechanical advantage by allowing a smaller input force to move a larger load.

Front

What is the difference between effort arm and load arm in levers?

Back

The effort arm is the distance from the fulcrum to the point where the effort is applied, while the load arm is the distance from the fulcrum to the load being moved.

Front

Where should the fulcrum be located for maximum mechanical advantage in a lever?

Back

The fulcrum should be located closer to the load than to the effort to maximize mechanical advantage.

Front

What is an example of a wheel and axle?

Back

Examples of a wheel and axle include a doorknob, pizza cutter, and bicycle wheel.
