A simply supported beam is loaded with apoint load, as shown in the figure. The beam is a steelwide flange shape (W 12 X 35) in strong axis bending. Calculate the maximum deflection of the beam andthe rotation at joint A if L =10 ft, a = 7 ft, b = 3 ft,and P = 10 kips. Neglect the weight of the beam.

A cantilever beam AB of length L = 6.5 ft supports a trapezoidal distributed load of peak intensity 4, and minimum intensity q/2,that includes the weight of the beam (see figure). The beam is a steel W 12 x 14 wide-flange shape (see Table F-1(a), Appendix F). Calculate the maximum permissible load q based upon (a) an allowable bending stress eallow = 18 ksi and (b) an allowable shear stress eallow = 7,5 ksi. Note: Obtain the moment of inertia and section modulus of the beam from Table F-1(a). W 12 x 14 -L= 6.5 ft-

4.5-11 The simple beam AB supports a uniform load of intensity q = 10 lb/in. acting over one-half of the span and a concentrated load P = 80 lb acting at midspan (see figure). Draw the shear-force and bending-moment diagrams for this beam. A |--1/2 = PROB. 4.5-11 = 40 in. P = 80 lb q=10 lb/in. L 12/2 = = 40 in. B
