Question

7. A pulley has a mechanical advantage of 1. What does this tell you about the size and direction of the input and output forces?

Answer 1

HELLO

HERE IS UR ANSWER :

There is no mechanical advantage

Explanation:

The mechanical advantage is possible only when the force needed to lift a load is lesser than the weight of the load.

For example, is we have a mechanical advantage of 2, the force needed to lift will be 1/2 of the weight of the load, and if we have a mechanical advantage of 4, the force needed will be 1/4 of the weight of the load.

In the attached image there are clear examples of mechanical advantage with pulleys.
