[Image Question - Placeholder] Two metals plates of thickness 't' and width 'w' are joined by a fillet weld of 45° as shown in fig. When subjected to a pulling force 'F' the stress induced in the weld will be
- A. $F/wt$
- B. $F/wt \sin 45$
- C. $F \sin 45 / wt$
- D. $2F/wt$
Answer: B. $F/wt \sin 45$
Explanation: Stress = Force / Throat Area. Throat area = $w \times t \sin 45$.
