Question

A force of 200 newtons is applied to a machine in order to lift a 1,000-newton load. What is the mechanical advantage of the machine?

Answer 1

The mechanical advantage of the machine is 5.

Explanation:

Mechanical advantage is calculated as follows:
`"Mechanical Advantage" = "output force"/ "input force"`
Here, your output force is the weight of the load, `1000N` and the input force is the force needed to lift it, `200N`.
`"Mechanical Advantage" = 1000/200`
`therefore "Mechanical Advantage" = 5`
