$A=ab,I_{x,C}=ab*112$ The tank pictured below is initially filled with water and is intended to be drained.

Determine the force on the circular plane at the end of the tank opposite the drain.

$P=0$ bar

$($a$)$ Rectangle

$($d$)$ Triangle

$($b$)$ Circle

$A=\frac{R^2}{2},I_{},C=0\mathrm{.}109757R^4$

$($e$)$ Semicircle

What is the force per unit area at the surface of the water on this side of the

dam? What is the force per unit area on the bottom of the side of the dam?
