(a) State Pascal’s law as applied to fluids at rest.
(b) A garage technician claims that a small input force applied on a narrow piston of a hydraulic lift can raise a heavy car resting on a wide piston. Explain, with reference to Pascal’s law, how the pressure created by the input force enables this force multiplication without violating the principle of conservation of energy.
(c) Identify any two practical factors that can reduce the ideal force multiplication predicted by Pascal’s law in real hydraulic machines.
