Question

Explain the construction and working of bramah press and how it is used in hydraulic jack

Answer 1

mark me brainliest answer

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.
