Imagine a hydraulically operated dentist's chair having a mass of 200.0 kg, and in it is sitting a 54.8-kg patient. The large piston beneath the chair has a diameter of 5.00 cm, whereas the small piston, moved by a pedal on which the dentist steps, has a diameter of 1.00 cm. What is the pressure in the interconnecting fluid when the dentist operates the chair? How much force must he exert on the small piston?© BrainMass Inc. brainmass.com October 16, 2018, 4:38 pm ad1c9bdddf
This solution includes three steps of quick calculations. The hydraulic dentist chair for Pascal's Principles are determined.
Four problems on mechanics.
Please see attached file for full problem description.
A 58-kg skier is going down a slope oriented 35° above the horizontal. The area of each ski in contact with the snow is 0.13 m2? Determine the pressure that each ski exerts on the snow.
Measured along the surface of the water, a rectangular swimming pool has a length of 15 m. along this length, the flat bottom of the pool slopes
downward at an angle of 110 below the horizontal, from one end to the other. By how much does the pressure at the bottom of the deep end exceed the pressure at the bottom of the shallow end?
A dentist's chair with a patient in it weighs 2100 N. The out plunger of a hydraulic system begins to lift the chair when the dentist'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?
A duck is floating on a lake with 25% of its volume beneath the water, what is the average density of the duck?
