4. The width of the rectangular gate shown in the figure is 4 m. Determine the magnitude of the resultant force on the gate by the salt water. Assume the weight density of the salt watery N/m³. 3.5 m 5m 60° PREC 444

H.WI: Find the horizontal and vertical forces and the resultant force (magnitude and location) on a 1 m wide section of the circular are gate. water m m 2 m W₂

The flow of water from a container is controlled by a 5-ft-wide L-shaped gate hinged at point A, as shown in the figure. If it is desired that the gate open when the height of the water is 10 ft, determine the weight W of the counterweight to achieve this. Take d= 5 ft and H = 16 ft. Give your answer in lb and without decimals.
