Question

then considered to complete the spec"Katin. Part C Maximum Distributed Load The bending design consideration requires the calculation of the beam's section modulus. This is a property based solely on the geometry of the beam, specifically the moment of inertia and the centroid Determine the maximum uniform distributed load w that can be applied to the W12 x 14 beam shown below if the maximum allowable bending stress is Ơallow-10 ksi and the maximum allowable shear is Tallow-2.1 ksi. The distance between the supports is 40 ft Figure 3) The geometric propertes of the beam are listed in thetable below. Once a loading is specified, we can use the flexure formula with the maximum bending moment, Mx to specify a lower bound on the section modulus: Area Depth Web Thickness Flange r-axis -y axis Mm Sreqiedllo Designation width thickness A (in2d (in) t (in) I (in) S (in (in) I(inS (in (in) y (in) t(in)n(in) where the maximum bending stress, Ơallow . is a parameter generally given in the design specifications.
