Question

determine the magnitude of the force applied by the technician To a circular (diameter=7.0 cm) piston connected to another circular (diameter=49.0cm) piston used to lift a load of 14700 Newton on a hydraulic lift. determine the magnitude of the force applied by the technician To a circular (diameter=7.0 cm) piston connected to another circular (diameter=49.0cm) piston used to lift a load of 14700 Newton on a hydraulic lift. determine the magnitude of the force applied by the technician To a circular (diameter=7.0 cm) piston connected to another circular (diameter=49.0cm) piston used to lift a load of 14700 Newton on a hydraulic lift.

Explanation / Answer

load to be lifted = 14700 N

piston area  A = 2pi*(49/2)2

Force per unit area = 14700/A

area of the piston where force is applied B = 2pi*(7/2)2

if Fb is force applied the Force per unit area = Fb/B this equal to the force per unit area connected to the lift

Fb/B = 14700/A

Fb = 14700*B/A = 14700*72 /492 = 300 N
