Amachine 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

3600 N force is put out by the machine

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 = ?

3600 N force is put out by the machine
