Hydraulic Lever: Effect of Force on Pressure

[jarman007]

I have a doubt about hydraulic lever


if a force f1 is applied at piston of smaller area a1 then pressure is transmitted to every part of fluid

due to aplication of f1 smaller piston move down and piston at other end move up

does the moving up of second piston have any effect on pressure of liquid

does the moving up of second piston have any effect on pressure of liquid

No, the two pistons will move at the same time (or very nearly so), so that the pressure is given by force/area.

If we apply force f1 on one piston and f2 on another such that p1 > p2 and one piston moves down and one up
then what is increase in pressure of liquid


will it be p1 + p2 ??

Yes. It will it be p1 + p2.

thanks a lot
