Question

The weight of a hydraulic barber's chair with a client is 2000 N. When the barber steps on the input piston with a force of 40 N, the output plunger of a hydraulic system begins to lift the chair. Determine the ratio of the radius of the output plunger to the radius of the input piston.

Answer 1

Answer: The weight of a hydraulic barber's chair with a client is 2000 N. When the barber steps on the input piston with a force of 40 N, the output plunger of a hydraulic system begins to lift the chair. Then the ratio of the radius of the output plunger to the radius of the input piston will be 7.07.

Explanation: To find the answer, we have to know more about the Pascal's law and the hydraulic lift.

What is pascal's law and how it is used in case of hydraulic lift?

• The law states that, the pressure exerted at any point on an enclosed liquid is transmitted equally in all directions.
• A hydraulic lift consists of two cylinders connected to each other by pipe.
• If the force F1 applied on the smaller piston of area A1, the pressure exerted will be,

                            $P_1=\frac{F_1}{A_1}$

• By pascal's law, the pressure transmitted to the large piston of large area A2 will be,

                            $P_2=\frac{F_2}{A_2}$

• Then,

                          $\frac{F_2}{A_2} =\frac{F_1}{A_1}$

How to solve the problem?

• We have to find the ratio of the radius of the output plunger to the radius of the input piston.
• We have the equation for this as,

                     $\frac{A_{Plunger}}{A_{piston}} =\frac{F_{Plunger}}{F_{piston}}$

                    $\frac{R_{Plunger}}{R_{piston}}=\sqrt{ \frac{F_{Plunger}}{F_{piston}}}=\sqrt{\frac{2000}{40} } =7.07$

Thus, we can conclude that, the ratio of the radius of the output plunger to the radius of the input piston will be 7.07.
