Question

Two cars, A and B, are held by the two pistons of a hydraulic press at the same

horizontal level. Car A weighs 3,400 N, and car B weighs 2,850 N. Calculate the

ratio between the area of the piston car A is sitting on and the area of the piston

car B is sitting on.

Answer 1

$F_A=3400N,F_B=2850N$

Area of car A

$A_A$

Area of car B

$A_B$

Pascal law

$P_A=P_B$

$\frac{F_A}{A_A}=\frac{F_B}{A_B}$

$\frac{A_A}{A_B}=\frac{F_A}{F_B}$

$\frac{A_A}{A_B}=\frac{3400}{2850}=1.192$

Ratio of areas

$\frac{A_A}{A_B}=1.192$
