Answer:

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 = ?

[tex]\texttt{Mechanical advantage}=\frac{F_o}{F_i}\\\\4.5=\frac{F_o}{800}\\\\F_o=800\times 4.5=3600N[/tex]

3600 N force is put out by the machine
