3. A tensile force is applied to the I-shaped piece of wood in a testing machine,
in the arrangement shown. The dimensions are b = 26 mm, t 12 mm, w =
34 mm, and the thickness (into the page) = 14 mm. (The wood has a
rectangular cross section.) The wood has a failure normal stress (ofail) of 1.2
MPa, a failure she ar stress (Tfait) of 18 MPa, and a failure bearing stress
(Orail.bra) of 0.9 M Pa. Determine the maximum safe load P that may be
applied, using a fi ctor of safety of 1.4.
