For the layout shown in the figure, calculate the value of pressure, position of the point of action, and angle at which the pressure force acts.
\begin{aligned} & \rho=1000 \frac{\mathrm{kg}}{\mathrm{m}^3} \\ & g=9.81 \frac{m}{s^2} \\ & \gamma=\rho \cdot g=9810 \frac{N}{m^3} \\ & h=1 m \\ & b=1 m \end{aligned}
