Question

Piston 1 has a diameter of 0.524cm Piston 2 has a diameter of 5.64 cm. In the absence of friction, determine the force required on piston 1 necessary to support an object, m, with weight 1072 N. (Neglect the height difference between the bottom of the two pistons, and assume that the pistons are massless)

The pressure is the same.

Force1/Area1=Force2/area2

figure the area of each (area=PI (diameter/2)^2)

Is the 1072N=F2?
bobpursley
yes.
Megan
So F1/2.15E-5=1072N/2.4E-3
F1= 2.15E-5*(1072/2.4E-3)
F1=9.63E10 N

I think I did this right but the answer comes up wrong when I submit it
