P-10 kip 1.5 kip/ft 9.75 kip -3 ft 3 ft- (a) M x 9.25 kip 6 ft A W10 x 45 simply supported beam with a span of 12 ft has a concentrated load of 10 kip and a distrib- uted load of 1.5 kip/ft, as shown in Fig. 15.14(a). The reactions have been calculated and the moment diagram drawn by parts [Fig. 15.14(b)]. Find the deflection at the middle of the beam.
