The triangular gate shown in the figure has its 6-ft side parallel and 30 ft below the water surface. Calculate the magnitude and location of the force acting on the gate if it is: (a) Vertical (b) Horizontal (c) On a 45° angle sloped upward

The vessel shown below contains linseed oil at 77° F. One side of the vessel contains a spout which is sealed with a 12-inch diameter flat circular gate hinged along its top edge. The horizontal axis of the hinge is located 6 feet below the water's surface. Determine the minimum required torque (moment) on the hinge to hold the gate shut. Neglect the weight of the gate and friction in the hinge. 6 feet Hinge 12-inch dia. gate Linseed oil

1. The rectangular gate below is 3 m long by 4 m wide (into the page). Obtain the force magnitude Q so that the gate remains closed as shown. The specific weight of the water is yw = 9.81 kN/m³. Patm hinge water at rest 1.5 m rectangular gate 60° 3 m no connection

The flat square of side length 2 m is submerged vertically in water,  2 m below the surface as shown. Find the fluid force against the surface. Use density of water is 9810 n/m^3.
