A bracket (shown in figure) is rigidly mounted on wall using four rivets. Each rivet is 6 mm in diameter and has an effective length of 12 mm.
Direct shear stress (in MPa) in the most heavily loaded rivet is
-
- 4.4
- 8.8
- 17.6
- 35.2
Correct Option: B
Given: Number of rivets = 4,
Diameter of each rivet, d = 6 × 10–3m
Direct load on the bracket = 1000 N
since there is no eccentricity
| ∴ Load on each rivet = | = 250N | |
| 4 |
| ∴ Shear stress = | = | = 8.8 MPa | ||
| A | π/4 (6)² |
