Question

The figure at the right shows the cross section of a steel beam "W10x60" (English units). The moment of inertia about the z axis is given as 344.6 in$^4$ (See "Tools & Data" Steel Section, MIT server 1.050. Note: Upon launching applet, go to options and choose "Choose Sec- tion > W". Scroll down to W10x60. Click on "Detail" and "English units"). A beam of this section, 10 ft. in length, is simply supported at its ends and carries a uniformly distributed load of 1000 lb/ft. $w_o = 1000 \text{ lb/ft}$. 10 ft. Sketch the shear force and bending moment diagram. Determine the maximum normal stress due to bending, $\sigma_{xmax}$; where does it act? Determine the shear stress $\tau_{xy}$ at i) a point on the neutral axis, at the left end of the beam ii) a point on the web where it meets the flange, again at the left end of the beam. For (i): Determine the principle stress components, the extreme values of the normal stress compo- nents, at the point. Compare these with the maximum normal stress due to bending.
