A beam ABC with an overhang from B to C sup- ports a uniform load of 200 lb/ft throughout its length (see figure). The beam is a channel section with dimensions as shown in the figure. The moment of inertia about the z axis (the neutral axis) equals 8.13 İn.4 200 Ihn (a) Calculate the maximum tensile stress o, and max- imum compressive stress due to the uniform load. (b) Find required span length a that results in...

A beam ABC with an overhang from B to C is constructed of a C 10
x 30 channel section (see figure). The beam supports its own weight
(30 lb/ft) plus a uniform load of intensity q acting on the
overhang. The allowable stresses in tension and compression are 18
ksi and 12 ksi, respectively. Determine the allowable uniform load
qallow (lb/ft) if the distance L equals 3.0 ft. The moment of
inertia, I = 3.94 in4.
