Question

If you apply 10 N to a machine and the machine applies 10 N to another object, what is the mechanical advantage? Can such a machine be useful? Why or why not.

A. The mechanical advantage is 1.
B. The mechanical advantage is 10.
C. The mechanical advantage is 100.
D. Such a machine can be useful for various tasks because of its mechanical advantage.

Answer 1

The mechanical advantage is 1. Such a machine can be useful for various tasks because of its mechanical advantage.

Step-by-step explanation:

The mechanical advantage is determined by the ratio of the output force to the input force. In this case, both the input force and the output force are 10 N. Therefore, the mechanical advantage is 1 (Option A).

A machine with a mechanical advantage of 1 is not considered to be useful because it does not multiply or augment the input force. It only transfers the force from one object to another without any change in magnitude. Such a machine can be useful when a force needs to be transferred without any amplification or reduction (Option D).
