Answer
$9:1$
Work Step by Step
The given values are
The given values are
Force on small piston $F_s=400\;lb$.
Force on large piston $F_l=3600\;lb$.
Formula for the mechanical advantage is
$\Rightarrow MA=\frac{F_l}{F_s}$
Substitute all the values.
$\Rightarrow MA=\frac{3600\;lb}{400\;lb}$
Simplify.
$\Rightarrow MA=\frac{9}{1}$
Hence, the $MA$ is $9:1$.
