Question

Quizplus · Accepted Answer

The formula for a hydraulic press is $F_1/F_2 = r_2^2 / r_1^2$, where $F_1$ and $F_2$ are the forces applied on the small and large pistons, respectively, and $r_1$ and $r_2$ are the radii of the small and large pistons, respectively. Given $F_1 = 21$ lb, $r_1 = 1$ in, and $r_2 = 8$ in, we can rearrange the formula to solve for $F_2$: $F_2 = F_1 \times (r_2^2 / r_1^2)$. Plugging in the given values, $F_2 = 21 \times (8^2 / 1^2) = 21 \times 64 = 1344$ lb.
