2. The gate in the figure below is 5 ft wide, is hinged at point B, and rest against a smooth wall at point A. Compute: a. The force on the gate due to seawater pressure (y = 64 lbf/ft³) b. The horizontal force P exerted by the wall at point A, and c. The reactions at the hinge B. Wall 6 15 41 6 Hinge 3. A 4-ft by 3-ft massless rectangular gate is used to close the end of the water tank shown below. A 200-lb weight attached to the arm of the gate at a distance 1 from the frictionless hinge is just sufficient to keep the gate closed when the water depth is 2 ft, that is, when the water fills the semicircular lower portion of the tank. If the water were deeper, the gate would open. Determine the distance 1. Hinge Hinge 1 ft 200 lb 3 ft Water Gate- 1:00 data 2 ft radius: 4 ft
