Q3 An open channel ABCD is used to contain a liquid of mass density p, as shown in Figure 4. It is made of steel and simply supported at B and C. It has a cross section shape and CLO3 axis direction as shown in Figure 5. The cross section is symmetrical about z axis. The beam has dimensions AB = 2.5 m and BC - L2 and CD 3 m. Under normal conditions, it is always full of liquid. The cross-section dimension is given in Figure 5 and the value of t in data sheet.
