4 (30 points). (a) Compute M, for the three beams shown in the figure below. In each case, c=4000 psi, f = 60 ksi, b = 12 in., d = 32.5 in., and h = 36 in. (b) From the results of part (a), comment on whether adding compression reinforcement is a cost-effective way of increasing the strength, pM,, of a beam. 12 in. 3.5 in. 2.5 in 2 No. 9 bars 4 No. 9 bars 32.5 in. 6 No....
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
