Solve Hydraulic Pump Homework: F1=33.5 N

[pmac]

Homework Statement

Piston 1 in the figure below has a diameter of 0.797 cm; piston 2 has a diameter of 4.32 cm. In the absence of friction, determine the force required on piston 1 necessary to support an object, m, with weight 983 N. (Neglect the height difference between the bottom of the two pistons, and assume that the pistons are massless).

Homework Equations

F1*d1 = Fp*d2, where d1 is the moment arm of F1, and d2 is
the moment arm of Fp.

The Attempt at a Solution

(33.5 N)(pi*.003895^2)=F2(pi*0.0216^2)
F2= 1.08 N
