Question

The motor on a construction-grade hydraulic shovel exerts 3.11 × 107 Pa of pressure on a fluid tank. The fluid tank is connected to a piston that has an area of 153 cm2. How much force does the piston exert?

Answer 1

$\text{according to Pascal's law}$

$p=\frac{F_1}{S_1}=\frac{F_2}{S_2}$

$F_1=p*S_1$

$p = 3.11*10^7Pa$

$S_1=153cm^2=153*10^{-4}m^2$

$F_1=3.11*10^7*153*10^{-4}=475830N$

Answer:475830 N
