The diagram below shows a hydraulic lift. A force is applied at side 1 and an output force is generated at side 2. Which of the following is true? (Given : $A_{2} > A_{1}$ )

CT57 question 12 diagram

Options:

Answer:

Solution:

Pascal's law gives equal pressure at the two pistons.
$\frac{F _{1}}{A _{1}} = \frac{F _{2}}{A _{2}}$
$F_{2} = F_{1} \frac{A _{2}}{A _{1}}$
Since A₂ > A₁, the output force exceeds the input force. Option B.
