A bolted Joint is shown below. The maximum shear stress, in MPa, in the bolts at A and B, respectively are
-
- 242.6 , 42.5
- 42.5 , 242.6
- 42.5 , 42.5
- 60.15 , 343.64
- 242.6 , 42.5
Correct Option: A
| FA = FB = FC = | kN | |
| 3 |
| FA = | = | |||
| rA² + rB² + rC² | 40² + 0² + 40² |
F'A = 18.75 kN = F'C
Shear load at A and C
FR = √(FA)² + (F'A)² = √(3.33)² + (18.75)²
FR = 19.04 KN
| τmax = | ||
| (π / 4) × 102 |
( τmax )A,C = 242.5 MPa
( τmax )B = 42.44 MPa
