Mechanical Advantage Questions

Front

What is mechanical advantage?

Back

The amount by which a machine multiplies input force.

Front

What is the formula for calculating work?

Back

W = Fd, where W is work, F is force, and d is distance.

Front

How do you calculate the work done when a force is applied?

Back

Multiply the force by the distance moved in the direction of the force.

Front

What is the unit of work in the International System of Units (SI)?

Back

Joule (J).

Front

If a machine has a mechanical advantage of 10, what does this mean?

Back

The machine multiplies the input force by 10.

Front

Is applying a force to a stationary object considered work?

Back

No, because there is no movement in the direction of the force.

Front

Calculate the work done if a force of 350 N moves an object 5 m.

Back

1750 J.

Front

What is the mechanical advantage if a lever allows a force of 1000 N to lift a 10,000 N car?

Back

10.

Front

What does it mean if a machine has a mechanical advantage less than 1?

Back

The machine requires more input force than the output force it provides.
