Homework Equations
F1=(A1/A2)F2
A=pi*r^2
The Attempt at a Solution
I solved for F1 using the above equation and got 12.8. THIS IS WRONG Is this because the column of fluid is higher in the larger piston? So i have to factor in the weight of the higher water as well? Can someone please point me in the correct direction?
thanks
