![Q4: For the RC beam section shown in figure below, find the location of neutral axis (N.A)
and the stresses in concrete & steel reinforcement at tension and compression side.
If concrete modulus of rupture (tensile strength) equals 10% of f'c, is it expected to crack at
tension side?
As (30 25 mm) = 1500 mm²
f'c = 30 N/mm²
fy = 420 N/mm²
Es = 200000 N/mm²
Ec= 20000 N/mm²
