Question

2. A round tube of diameter 2 inches is welded to a wall and subjected to a tensile force of 5000 lbs as shown. The weld rod is E60. The weld leg is 0.25 inches. What is the factor of safety guarding against weld metal yielding as a result of this force? d) 4.13 b) 2.48 e) None of these c) 3.38 a) 1.62 lbs F 5000

Answer 1

The load appiled is transmitted directly to the weld joint.

So the tensile force acts on the weld joint and the weld joint is approximated as a triangle with base and height as leg size.It is approximated to fail about a plane which has least cross sectional area.

Shear failure is most likely to occur on the least cross sectional area plane,so we consider shear stress in that plane.

Hope it helps.
