The tank in Figure P 14.13 is filled with water of depth d 5 2.00 m. At the bottom of one sidewall is a rectangular hatch of height h 5 1.00 m and width w 5 2.00 m that is hinged at the top of the hatch. (a) Determine the magnitude of the force the water exerts on the hatch. (b) Find the magnitude of the torque exerted by the water about the hinges.
