Question

A dentist’s chair makes use of Pascal’s principle to move patients up and down. Together, the chair and a patient exert a downward force of 2269 N. The chair is attached to a large piston with an area of 1221 cm2. To move the chair, a pump applies force to a small piston with an area of 88.12 cm2. What force must be exerted on the small piston to lift the chair

Answer 2

Answer: 163.75N

Explanation:

Area of the large piston=1221cm²=0.1221m²

Area of the small piston= 88.12cm²=0.008812m²

Force on the large piston=2269N

Therefore pressure on large piston=

Force/area=2269/0.1221

= 18583.12N/m²

According to Pascal's law

Pressure on the large piston= pressure on the small piston.

Therefore,

Pressure×area= force

18583.12×0.008812

=163.75N

This force must be exerted on the smaller piston to lift the chair.
