Hydraulic systems utilize Pascal's principle by transmitting pressure from one cylinder (called the primary) to another (called

Paul [167]

Answer:

F1= 122.93 N

Explanation:

Pascal´s Principle

Pascal´s Principle can be applied in the hydraulic press:

If we apply a small force (F1) on a small area piston A1, then, a pressure (P) is generated that is transmitted equally to all the particles of the liquid until it reaches a larger area piston and therefore a force (F2) can be exerted that is proportional to the area (A2) of the piston:

P=F/A

P1=P2

$\frac{F_{1} }{A_{1}} = \frac{F_{2} }{A_{2}}$ Formula (1)

Data

D1 = 1.85 cm : primary cylinder piston diameter

D2 = 24.5 cm : secondary cylinder piston diameter

m = 2200-kg : car mass

Piston area calculation

$A_{1} = \frac{\pi *(D_{1})^{2} }{4}$

$A_{1} = \frac{\pi *(1.85)^{2} }{4}$

A1= 2.688 cm²

$A_{2} = \frac{\pi *(D_{2})^{2} }{4}$

$A_{2} = \frac{\pi *(24.5)^{2} }{4}$

A2 = 471.435 cm²

Calculating of the weight of the car (W)

W = m*g = 2200-kg * 9.8 m/s² = 21560 N

Calculation of the force in Newtons to be exerted on the primary cylinder piston

Data:

A1= 2.688cm²

A2= 471.435 cm²

F2 = W= 21560 N

We replace data in the formula (1)

$\frac{F_{1} }{A_{1}} = \frac{F_{2} }{A_{2}}$

$F_{1} =\frac{F_{2}*A_{1} }{A_{2} }$

$F_{1} =\frac{21560N*2.688 cm^{2} }{471.435 cm^{2} }$

F1= 122.93 N
