If connected by one leg it is assumed that this leg will carryall the stress. Assume a thickness of i\ and as the area is ins. divide and add, to the width thus obtained, the diameterof the hole. Then = + = This isplainly not suitable, for it does not fit any standard angle. Trya thickness of f and we get - 0 625 = 5 + = is nearly six inches, so we will use a 6 x 3J x f angle. The practice of using |-in. and xVi^- gusset plates in roof trussesis very common, yet considerations of economy, as well as effici-ency, would seem to ndicate the use of thick plates.
