59. A beam is to be designed for loads causing a maximum factored shear of 60.0 kips, using concrete with 5000 psi Proceeding on the basis that the concrete dimensions

will be determined by diagonal tension, select the appropriate width and effective depth (a) for a beam in which no web reinforcement is to be used, (b) for a beam in which only the minimum web reinforcement is provided. as given by Eq. (5.13 a), and (e) for a beam in which web reinforcement provides shear strength V,the ACI Code requirements, and let d = 2b in each case. Assume that P = 0.012.
