If yield stress of steel is 415 MPa, then strain in tensile reinforcement at the limit state of collapse shall be at least _____________. For steel, the Young’s Modulus, E = 2 × 105 MPa.
-
- 3.0037 to 3 .0039
- 2.0037 to 2.0039
- 1.0037 to 1.0039
- .0037 to .0039
Correct Option: D
(.0037 to .0039)
For steel, the Young's Modulus, E = 2 × 105 MPa
| Min. tensile strength = |  |  | + 0.002 | |
| E |
| = |  |  | + .002 | |
| (2 × 105) |
= 0.0018 + 0.002 = 0.0038
