Fill in the blank to complete the sentence explaining the mechanical advantage of a hydraulic system:
A hydraulic device acts as a force multiplier because the ratio of the output force to the input force is directly equal to the ratio of the (1) of the two pistons.
Correct Answer
(1) areas
Explanation
Since pressure is uniform (\(F_1/A_1 = F_2/A_2\)), rearranging the formula reveals that the force multiplication factor (\(F_2/F_1\)) is determined entirely by the ratio of the cross-sectional areas (\(A_2/A_1\)).
