Q$1.)(3)$ point

The tank is filled with water.

$1-$ Determine the resultant force acting on the triangular plate A and the location of the center of pressure, measured from the top of the tank.

$2-$ Determine the resultant force acting on the semicircular plate B and the location of the center of pressure, measured from the top of the tank.

$3-$ Determine the resultant force acting on the trapezoidal plate C and the location of the center of pressure, measured from the top of the tank.

Determine Using

Integration Formula that

my professor gave me

${\displaystyle \underset{a}{\overset{b}{}}}$PdA

$dA=2xdy$

$P=(specific$ weight$)h$

Thank you for helping me understand how to do this. I tried them all on my own but got them all wrong.
