Question

Question 4 10 pts A rectangular concrete water tank for a small irrigation project in Bolivia has inside dimensions of om long by 5m wide by 2m tall. What is the magnitude of the force acting on the long wall (6m x 2m) of the tank when the tank is completely full of water? 128.7 KN 117.7 KN 136.5 kN 124.1 KN Question 5 10 pts How far below the surface of the water would the resultant force in problem 4 act? 1m 0.67 m 1.21m O 1.33 m
