Which of the following stresses are associated with the tightening of a nut on a stud? 1. Tensile stresses due to stretching of stud 2. Bending stresses of stud 3. Transverse shear stress across threads 4. Torsional shear stresses in threads due to frictional resistance
- A. 1, 2 and 3
- B. 1, 2 and 4
- C. 1, 3 and 4
- D. 2, 3 and 4
Answer: C. 1, 3 and 4
Explanation: Tightening causes axial tension, torsion due to friction, and shear across threads.
