Question 2: The two sides of a V-shaped water trough are hinged to each other at the bottom where they meet, as shown in Fig. below, making an angle of 45 with the ground from both sides. Each side is 0.75 m wide, and the two parts are held together by a cable and turnbuckle placed every 5 m along the length of the trough. Calculate the tension in each cable when the trough is filled to the rim. (25 points) - Cable 0.75 m 450 45 Hinge (a) the average water exit velocity (b) the horizontal resistance force required of the firefighters to hold the nozzle.
