Pascals principle states that pressure applied to an enclosed
liquid is transmitted equally to every part of the liquid.
Hydraulic systemsThis allows the lifting of a heavy load with a
small force, as in an auto hydraulic lift
P1=P2F1=F2A1A2
APPLICATIONSHYDRAULIC SYSTEM The output force is given by :
F2 = A2 X F1A1F1 = input forceA1 = small piston areaF2 = output
forceA2 = large piston area
Automobile hydraulic liftForce multiplied by hydraulic press,
based on Pascal's principle. The fluid in the small cylinder must
be moved much further than the distance the car is lifted.
