For Problems 8-21 through 8-30, assume that the indi-
cated shape is the cross section of a beam made from wood
having an allowable shearing stress of 70 psi, which is that of
Grade No. 2 southern pine listed in Appendix A-15. Compute
the maximum allowable shearing force for each shape. Use
the general shear formula.
