Question

If a simple machine reduces the strength of a force, what must be increased?

A) the work the simple machine performs.

B) the speed of the input force.

C) the size of the simple machine.

D) the distance over which the force is applied.

Answer 1

Answer: D. the distance over which the force is applied

Answer 2

Option D

Step-by-step explanation:

The answer is option D or "the distance over which the force is applied." Since basic machinery is created to lessen the work for us humans reducing the strength of the force means that the distance which where the force is needed to be applied needs to be increased. Increasing the distance for the machine makes it all around more efficient. One of the most common examples of basic machinery is a rake. When using a rake, you do not need to apply as much force into it to make the rake efficient. If you increase the distance on where you are raking, then the amount you are raking increases, which means it's all-around efficiency increases.

Hope this helps.
