Question:-
The following figures shown welded joints (xxx indicates welds), for the some load and same dimension plate and weld:

The joints shown,
Option (A)
Figure I is better because the weld is in shear and the principle stress in the weld is not in line with P.
Option (B)
Figure I is better because the load transfer from the tie bar the plate is not direct
Option(C)
Figure II is better because the weld is in tension and safe stress of weld in tension is greater than in shear
Option(D)
Figure II is better because it has less stress
Correct Option:
(C)
Question Solution:
Figure-2: Arrangement is called transverse fillet weld (the load acting is perpendicular to the weld). Transverse fillet weld designed for tensile strength.
Figure-1: It is called parallel fillet weld and they are designed for shear strength.
The magnitude of permissible tensile stress (220 N/mm2) is larger than shear strength (140 N/mm2) of weld.
