# Hydrostatic Force

by coding   Last Updated July 09, 2019 00:20 AM - source

Struggling with this question: Find the force due to hydrostatic pressure on the side of a trough of length $$L$$ if the end is a semicircle of radius $$R$$ and it is filled to the top with a fluid of density $$\rho$$.

I worked out the width to $$2\times\sqrt(R^2 - x^2)$$ but do not know where to go from here
