10Pascal’s law applies only to gases.
In hydraulic machines, a small force applied on a small piston produces a larger force on a bigger piston.
Brake fluid is incompressible, which makes hydraulic brakes effective.
Hydraulic jacks can lift loads by repeated pumping.
The large piston always has a smaller cross-sectional area than the small piston.
Pascal’s law explains why water in a bag comes out perpendicularly from holes.
Hydraulic presses are used for bending metal sheets.
Pascal’s law is only theoretical and has no practical application.
Excavators use hydraulic cylinders to multiply force for digging.
Hydraulic lifts are inefficient because force cannot be transmitted.
