In a doubly-reinforced beam if and the effective depth and is depth of critical neutral axis, the following relationship holds good________?
A(m + c)/t = n/(d + n)
Bmc/t = (d – n)/t
Cmc/t = n/(d – n)
D(t + c)/n = (d + n)/n
Correct answer
C. mc/t = n/(d – n)
Explanation
The correct answer is mc/t = n/(d – n).
