with a force of 320 N. If the bike has an
output force of 640 N, what is the
mechanical advantage of this bike?

Answer 1

Answer: 2

Explanation:- Mechanical advantage is the ratio of the output force to the input force.

Mechanical advantage=

Given:

Input force = 320 N

output force= 640 N

`{\text {Mechanical advantage}}=(640N)/(320N)=2`
