In butt weld joint, what will be the strength equation? if the thickness of the plate is t, permissible tensile stress for the weld is σt, and the length of the weld is l.

In butt weld joint, what will be the strength equation? if the thickness of the plate is t, permissible tensile stress for the weld is σt, and the length of the weld is l. Correct Answer σttl

In butt joints, the tensile force is observed. The strength of the butt joint is a product of the area resisting the tensile stress and the permissible tensile stress for the weld is σt.
