The accompanying figure shows part of a common type of roof truss, constructed mainly of timber and steel rods. Determine:
a. The average compressive stress in the 8”
8” diagonal member if the load in it is 20 k.
b. The tensile stress in the diameter threaded steel rod if the load in it is 4 k.
c. The bearing stress between the timber and the
square steel washer if the hole in it is diameter.
d. The bearing stress between the brick wall column and the timber if the load in the column is 15 k.
e. The length L required to keep the dashed portion of the member from shearing off due to the horizontal thrust of 16 k against the steel shoe. The allowable.
