Question

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

The number of input force is the same as output. Formula for MA (Mechanical Advantage) is Input Force/Output Force. If it equals once, then both numbers are equal making it the same. In order to raise MA, you must lower efficiency, something you learn around grade 8. Good luck!

P.S. Direction is the same for both, meaning if you pull something, the object you pull will come towards you.
