Question

The image illustrates a schematic diagram of a gate in a fluid mechanics context. Here's a detailed explanation of the components:

- **Pivot**: A point located at the corner of the L-shaped gate, serving as the axis of rotation.

- **Gate Description**: The gate is shown as a thick, L-shaped structure, partly submerged in a fluid.

- **R**: Denotes the radius of the curved part of the gate, measured vertically from the horizontal base to the central point of curvature.

- **\( \gamma_B \)**: Represents the specific weight or unit weight of the fluid on the curved section.

- **h**: Indicates the height of the fluid above the horizontal section of the gate.

- **Fluid Surface**: The upper part of the shaded grey area represents the free surface of the fluid, indicating fluid presence above the gate.

This diagram likely belongs to a study of fluid statics, exploring buoyancy, pressure forces on submerged surfaces, or the equilibrium of floating bodies. The pivot point suggests the possibility of analyzing moments caused by fluid forces acting on the gate.

A solid barrier is made from styrofoam (\(\rho_s = 30 \, \text{kg/m}^3\)) and consists of one quarter of a circular cylinder with radius \(R = 10. \, \text{cm}\) and uniform width \(w = 20. \, \text{cm}\) perpendicular to the view shown. The barrier is hinged at \(O\), which is offset from the vertical wall a distance \(d = 5.0 \, \text{cm}\). When the water depth is \(h = 15 \text{cm}\), what is the magnitude and direction of the normal force, \(N\), that the bottom surface exerts on the barrier?
