Mechanical Advantage : Inclined Plane Family

Front

What is Mechanical Advantage (MA)?

Back

Mechanical Advantage (MA) is the ratio of the output force (load) to the input force (effort) in a machine, indicating how much a machine multiplies force.

Front

What is the formula for calculating Mechanical Advantage?

Back

MA = Resistance Force / Effort Force.

Front

What is an inclined plane?

Back

An inclined plane is a flat surface that is tilted at an angle to the horizontal, used to help raise or lower objects.

Front

How does an inclined plane reduce the effort needed to lift an object?

Back

An inclined plane allows a smaller force to be applied over a longer distance, reducing the effort needed to lift an object vertically.

Front

What is the primary mechanical advantage of using an inclined plane?

Back

You can apply a small force to penetrate something that normally requires a large force.

Front

If a force of 50 N is applied to lift a 350 N rock, what is the Mechanical Advantage?

Back

MA = 350 N / 50 N = 7.

Front

What is the input force in a lever system?

Back

The input force is the force applied to the lever to lift the load.

Front

What is the output force in a lever system?

Back

The output force is the force exerted by the lever to lift the load.

Front

What does a Mechanical Advantage of 2 indicate?

Back

A Mechanical Advantage of 2 indicates that the machine doubles the input force.

Front

What is the significance of a Mechanical Advantage less than 1?

Back

A Mechanical Advantage less than 1 indicates that the machine requires more input force than the output force it provides.
