Summary. f=p*s, this is the most fundamental principle, you see, the motor drives the oil pump to produce 10MPa hydraulic oil, the hydraulic oil enters another container, the size of the force generated is related to the surface area, as shown in the figure, there is a difference between S1 and S2 on both sides, and the force of S1 can be calculated by the formula F=PS, and the force of S1 and S2 is the same, then P2=F1 S2, the greater the difference between S1 and S2, the greater the force of F2, and that's it.
