The height of a water reservoir is controlled by a cylindrical gate hinged to the reservoir. We take the density of water to be 1000 kg/mĆĀ³ throughout. The length of the cylinder is equal to 1 m.
a) [15 marks] Determine the magnitude of the hydrostatic force acting on the submerged body.
b) [10 marks] Determine the line of action of this hydrostatic force (the value of the angle it makes with the horizontal).
