Homework Statement
My English of influid meachanics is poor, so I only can hope that
you can understand the figure (please forgive me!)
Please find the force Fz which the hemisphere endures
Homework Equations
My way: "on" the hemisphere, I want to use triple integral(but I'm not sure the way's right) and cut into the part into many innumerable tiny 3D right angled trapezoid
(i.g. KJPQ-K'J'P'Q')
Then I think that:
ρgV( the part + the hemisphere)=Fz
The Attempt at a Solution
Because my math is weak, I hope somebody can help me.
If you can understand the problem, please tell me whther my way or my calculation is right or not, thank you!
The following is my calculation.
ps: one integral
