Question

Explain how does a hydraulic jack work.

Answer 1

hi ^_^

Hydraulic jacks depend on force generated by pressure. ... Hydraulic jacks depend on this basic principle to lift heavy loads: they use pump plungers to move oil through two cylinders. The plunger is first drawn back, which opens the suction valve ball within and draws oil into the pump chamber.

hope it helps ^_^
