A solid straight steel rod of diameter 100 mm is bent in single curvature into a circular arc by a moment of 50 kNm applied at its ends. If elastic modulus, E, for steel is 2 × 105 MPa, the radius of curvature (mm) of the arc assuming π = 3.14 is _____________
-
- 19615 to 19635
- 29615 to 31635
- 615 to 635
- 9615 to 9635
Correct Option: A
(19615 to 19635)
| M = | ||
| R |
Where M = Moment = 5000 Nm
E = Elastic Modulus = 200000000000 Pa
| I = Moment of inertia = | ||
| 64 |
| = | = 4906250 | |
| 64 |
| R = | = 19625 mm | |
| M |
