4.42 Figure 4.46 shows a tank of water with a circular pipe con- nected to its bottom. A circular gate seals the pipe open- ing to prohibit flow. To drain the tank, a winch is used to pull the gate open. Compute the amount of force that the winch cable must exert to open the gate.

417 For the orange-drink tank shown in Fig. 4.32, compute
the magnitude and location of the total force on the verti
cal back wall. The tank is 3.0 m long.
48 For the oil tank shown in Fig. 4.35, compute the magni-
tude and location of the total force on each vertical end
wall, The tank is 1.2 m long.
4.39 For the oil tank shown in Fig. 4.35, compute the magni-
tude and location of the total force on the vertical back
wall. The tank is 1.2 m long.
4.40 Figure 4.44 shows a rectangular gate holding water behind
it. If the water is 6.00 ft deep, compute the magnitude and
location of the resultant force on the gate. Then compute
the forces on the hinge at the top and on the stop at the
