Hello
Problem description: determine the lenght of h with respect to b so that the water flows.
ive gotten as far as come up with an equation for the sum of moments and it goes as follows: \(\displaystyle bh*1/2b1/2hb*1/3b=0\) the answer is wrong and i dont know why. moment arm on the b is 1/2b and the moment arm on h is 1/3h because of the way water pressure works , meaning its a uniform load in the shape od triangle. the answer to this problem is supposed to be \(\displaystyle sqrt3 *b\). Any help appreciated.
