The accompanying figure shows part of a common type of roof truss, constructed mainly of timber and steel rods. Determine: a. The bearing stress between the brick wall column and the 8” x 10” timber if the load in the column is 18 kips. b. The length L required to keep the dashed portion of the 8” x 10” member from shearing off due to the horizontal thrust of 20 kips against the steel shoe. The allowable shear stress is 125 ksi.
