Transcribed Image Text:Problem 14.3.A
A 4 × 4 x 2-in. angle of A36 steel is to be welded to a plate with E 70
XX electrodes to develop the full tensile strength of the angle. Using
%-in. fillet welds, compute the design lengths for the welds on the two
sides of the angle, assuming development of tension on the full cross sec-
tion of the angle.
