Two metal plates of thickness ‘t’ and width ‘w’ are jointed by a fillet weld of 45° as shown in given figure. When subjected to a pulling force ‘F’ the stress induced in the weld will be:

Option (A)
F / wt sin 45°
Option (B)
F / wt
F sin 45° / wt
2F / wt
Correct Option:
Question Solution:
The throat h

sin 45° = h/t
h = t sin 45°
Area of minimum throat = w x h = wt sin 45°
Shearing force = (F/wt sin 45°)
