The metal with the hardest CW will be the strongest = Rectangular
Step-by-step explanation:
Circular(di, mm) Rectangular(di, mm)
Original Dimension 18.0 20 x 50
Deformed Dimension 15.9 13.7 x 55.1
%CW =
Circular %CW =
= 21.97%
Rectangular %CW =
= 24.51%
The metal with the cross-section rectangular would be the best because it has the largest percentage of CW.
