A hydraulic lift office chair has its seat attached to a piston with an area of

Question

11.2 cm2
. The chair is raised by exerting force on another piston, with an area
of 4.12 cm2
. If a person sitting on the chair exerts a downward force of 219 N,
what force needs to be exerted on the small piston to lift the seat?

Answer 1

Force on big piston/force on small piston = 11.2/4.12 = 2.72 which is the mechanical advantage of our hydraulic jack machine

219/2.72 = 80.5 Newtons

That is a pretty light person by the way.

Answer 2

80.56 N

Answer 3

11.2/4.12=2.72, 219/2.72=80.5 N
thanks Ms. Smith!

Answer 4

A1 = 4.12 x 219 / 11.2 = 80.5N

Answer 5

So to get the answer you have to subtract the numbeer by itself then add that number you subtracted it to the answer that you got then add 2 the 3 then subtract 5 then you multiply the divide then you got your answer and ready to go. You are welcome I am the smartest person in the world
