34. A barber’s chair with a person in
it weighs 2100 N. The output plunger of a hydraulic system begins to lift the
chair when the barber’s foot applies a force of 55 N to the input piston.
Neglect any height difference between the plunger and the piston. What is the
ratio of the radius of the plunger to the radius of the piston? |

Pascal’s principle says any
change in pressure in a fluid is transmitted
undiminished throughout the entire fluid. |
