A structural designer wishes to locate the roller support B such that the beam AD) in Fig. P6.4-13 will have the same maximum magnitude of positive moment and negative moment when subjected to concentrated loads PA and Pc acting on the beam as shown. Once the overhang length b has been determined, the designer must choose an appropriate beam to satisfy a flexural stress allowable of Fallow (tension or compression). (a) Determine the overhang length b. (b) From Table D.2, select the best wide-flange section for this application. Let PA = 30 kN, Pc = 40 kN, L = 1.5 m, oallow = 80 MPa. Pc PA A B 2L с L- D
