When a force of 350 lb is applied to the small piston of a hydraulic press, a force of 14,000 lb is exerted by the large piston. Find its mechanical advantage.
A) $\frac { 40 } { 1 }$
B) $\frac { 42 } { 1 }$
C) $\frac { 30 } { 1 }$
D) $\frac { 25 } { 1 }$
E) $\frac { 38 } { 1 }$

The mechanical advantage (MA) of a hydraulic press is calculated by dividing the output force by the input force. In this case, MA = $ \frac { 14,000 \, \text{lb} }{ 350 \, \text{lb} } = 40 $. Therefore, the mechanical advantage is $ \frac { 40 } { 1 } $.
