why do we deduct 2d for 90 degree bend
- Thread starter arbaaz.apz
- Start date
When we bend a steel bar, the length of the bar slightly increased due to stretching in the bending area (refer to below image).
The expansion of length depends on the grade of steel and the degree of bend.
The length increases with the increase of bending degree and decreases with the higher grade steel. (Fe250, Fe450, Fe500)
1. For 45° bend = 1 x d
2. For 90° bend = 2 x d
3. For 135° Bend = 3 x d
4. For 180° bend = 4 x d
