What is Mechanical Advantage?

Back

Mechanical Advantage (MA) is a measure of the force amplification achieved by using a tool, mechanical device, or machine system. It is calculated as the ratio of the load force to the effort force.

Front

How do you calculate Mechanical Advantage?

Back

Mechanical Advantage is calculated using the formula: MA = Load Force / Effort Force.

If the weight of the block is 10N, how much force is needed to lift it using a pulley with MA=2?

Back

5N

Front

What is the relationship between mechanical advantage and the amount of force needed to lift a load?

Back

A higher mechanical advantage means less force is required to lift a load.

Front

What type of lever allows for a greater mechanical advantage?

Back

A first-class lever can provide a greater mechanical advantage depending on the position of the fulcrum.
