The small piston of a hydraulic press has an area of 3.2 in2. If the applied force is 2.0 lb, what must the area of the large pi
BartSMP [9]

Given data:

The area of the hydraulic press is,

A_1=3.2in^2

The applied force is,

F_1=2\text{ lb}

The pressing force on the large piston is

F_2=795\text{ lb}

Given hydraulic press works on Pascal's law principle.

From the Pascal's law, the equation can be given as,

\frac{F_1}{A_1}=\frac{F_2}{A_2}

Here,

A_2

is the area of the larger piston.

Substituting the values in the above equation, we get:

\begin{gathered} \frac{2\text{ lb}}{3.2in^2}=\frac{795\text{ lb}}{A_2} \\ A_2=1272in^2 \end{gathered}

Thus, the area of the large piston is

1272in^2
