Problem 5.6-9A beam ABCwith an overhang from Bto Cis constructed of a C10±30 channel section (see figure). The beam supports its own weight (30 lb/ft) plus a triangularload of maximumintensity q0acting on the overhang. The allowable stresses in tensionand compression are 20 ksi and 11 ksi, respectively.Determine the allowable triangularload intensity q0,allowif the distance Lequals 3.5 ft.418CHAPTER 5Stresses in Beams (Basic Topics)Solution 5.6-9NUMERICAL DATAfrom Table E-3(a) MAX.
