Question

A machine has a mechanical advantage of 4.5. What force is put out by the machine if the force applied to the machine is 800 N?

0.006 N
180 N
805 N
3600 N

Answer 1

3600 N is the answer I just took the test

Answer 2

3600 N force is put out by the machine

Step-by-step explanation:

Mechanical advantage is the ratio of output force to input force.

Here

Mechanical advantage = 4.5

Input force, Fi = 800 N

Output force, Fo = ?

`\texttt{Mechanical advantage}=(F_o)/(F_i)\\\\4.5=(F_o)/(800)\\\\F_o=800* 4.5=3600N`

3600 N force is put out by the machine
