Two technicians are discussing hydraulics. technician a says that if pistons of the same size are used, motion and force can be increased or decreased. technician b says that if a small piston acts upon a larger piston, the force of the larger piston will increase, but the distance it travels will decrease. who is correct? a. technician b only b. technician a only c. both technician a and b d. neither technician a nor b

the correct option is A. Only technician B is correct.

Hydraulics works on the pascal law, which states that in a direction the hydro static fluid pressure remains constant.

Px=Py=Pz

Since small piston has small area compare to the large piston

Pbig=Psmall

Fbig/Abig=Fsm/Asm

Fbig=

thus the force on the large piston will increase, but it travel small distance.
