how can change 12mmdia@150c/c bar spacing to 16mmdia

Answer Posted / daniel lemma

Let assume for 1m (1000mm) span
d1=12mm
s1=150 approx No. =8pcs

d2=16mm
s1=? approx No. =?
We have to use this formula
d1^2 / s1 = d2^2 /s2 So s2=266.66 and
approx Spacing 250mm, and
New approx No of bar will be 4pcs

Is This Answer Correct ?    13 Yes 2 No
