Pascals principle and hydraulic lift

[jambaugh]

I really liked this part. Does something similar happen when the pistons are not in line but like in the picture in post #21?

Yes. If you want to calculate it in full glory, you can carry out a surface integral of pressure times inward normal to the surface. This gives the net force on the fluid. I in integrating you leave out the pistons then this total force must equal the forces on the pistons.
