Question

A screw has a mechanical advantage of 12.5. How much force must you

apply to the screw so that it has an output force of 1000 N?

Answer 1

80 N, I just took the test

Answer 2

Answer: The force that must be applied is 80N

Explanation:

Here, we are talking about simple machines; a screw is an example of a simple machine. Other examples include lever, nail puller, wheelbarrow, crank, etc.

Here, we are talking about simple machines; a screw is an example of a simple machine. Other examples include lever, nail puller, wheelbarrow, crank, gear, etc.

Simple machines are devices that can be used to multiply or augment a force that we apply – often at the expense of a distance through which we apply the force.

The mechanical advantage for any simple machine is the ratio of output to input force magnitudes. That is,

Mechanical advantage (MA) = Force output / Force input

From the question,

Mechanical advantage (MA) = 12.5

Force output = 1000N

Force that must be applied, that is, force input = ??

Therefore,

12.5 = 1000N/ Force input

Force input = 1000N/12.5

Force input = 80N

Hence, the force that must be applied is 80N
