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

Respuesta :

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=[tex] \frac{Abig}{Asmall}*Fsmall [/tex]

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