Question
Required beam section modulus (include units)
Transcribed Image Text:Required beam section modulus (include units)
A steel beam is used under a uniformly distributed load (UDL) of 1500 #/ft. The beam can be assumed to be simply supported with a span of 24 ft. (see sketch below ) From beam table, case 1 the maximum moment for a UDL on a simply supported beam is equal to Wl²/8. When w is expressed in Ibs/ft and I is measured in feet then the calculated moment is given in foot-lbs. We can multiply by 12 to convert the answer to inch-Ibs. If the maximum allowable stress in the beam is 30 ksi what is the required section modulus for the beam? You can assume that the beam is continuously supported laterally. Maximum moment |(include units)
