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 March 4, 2021, 6:09 pm ad1c9bdddf
