The components and their dimensions of a hydraulic jack are shown in the figure. The specific gravity of the fluid in the jack is SG=0.8. A force F=400 N is applied at the left end of the handle, which is hinged at the right end. Determine:

(a) The fluid pressure p1 on the lower surface of the small piston.

(b) The fluid pressure p2 on the lower surface of the large piston.

(c) The weight W of the load that can be supported.
