T-section of a beam is formed by gluing wooden planks as shown in the figure below. If this beam transmits a constant vertical shear force of 3000 K, the glue at any of the four joints will be subjected to a shear force (in kN per metre length) of
-
- 3.0
- 4.0
- 8.0
- 10.7
Correct Option: B
| Shear flow, q = | I |
| I = | + 2 |  | + 15 × 50 + 1252 |  | |||
| 12 | 12 |
= 3.5 × 108 mm4
V = 3000 N
θ = 50 ×75 × 125 = 468750 mm2
| ∴ q = | = 4 kN/m | 3.5 × 108 |
