The stresses acting on element B (see figure part (a)) on the web of a wide-flange beam are found to be 14,500 psi in compression in the horizontal direction and 2,640 psi in compression in the vertical direction (see figure part (b)).
Also, shear stresses with a magnitude of 3,500 psi act in the directions shown.
Determine the stresses (in psi) acting on an element oriented at a counterclockwise angle of 30\deg from the horizontal. (Assume that the +x-axis is to the right and the +y-axis is up along the page. Use the sign convention for stresses acting on inclined sections.)
\sigma x1 =
psi
\sigma y1 =
psi
\tau x1y1 =
psi
Show these stresses on a sketch of an element oriented at this angle.
