Question

100 POINTS PLEASE HELP ASAP!!!!

What is the formula for mechanical advantage?
A. Ma = force output + force input
B. MA = force output / force input
C. MA = force input / force output
D. MA = force output * force input

Answer 1

B. MA = force output / force input

Step-by-step explanation:

The ideal mechanical advantage equals the length of the effort arm divided by the length of the resistance arm of a lever. In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr.

Answer 2

answer: MA= force output/ force input .
