High yield deformed bars have a
High yield deformed bars have a
Open in App
Solution
The correct option is C percentage elongation less than of mild steel
Mild steel has definite yield point and the plastic strain may extend upto a strain of 0.15. Cold worked high strength deformed bars do not have a definite yield point and the characteristic strength refers to 0.2% proof stress. Their plastic strain is less than that of mild steel bars.
