A storm drainage channel has the shape shown in Figure 5. It is made of unfinished concrete and has a slope of 0.5 percent. During normal times, water remains only in the small rectangular section. When there is a big rainfall, the upper section allows large volumes to be carried by the channel. a. Compute the hydraulic radius and normal discharge when the water depth is 0.50 m. b. Compute the hydraulic radius and normal discharge when the water depth is 2.50 m.

A bar ABCD has a circular cross section of 75 mm diameter over half its length and 50 mm diameter over the remaining half of its length. A torque of 1 kNm is applied at C midway between B and D as shown in Fig. P.11.4. Sketch the distribution of torque along the length of the bar and calculate the maximum shear stress and the maximum angle of twist in the bar. G=70 000 N/mm². Ans. Tmax = 23.2 N/mm² in CD, 0.38° at C.
