Design Workshop Assessment: Tutorial Question $4$

A$.$ Determine the neutral axis depth and the concrete and steel stresses induced by positive bending moment of $100$ kN$.$m$.$ Adopt modular ratio method and consider that the section is cracked under bending a moment of $100$ kN$.$m$.$

B$.$ Determine the neutral axis depth and the concrete and steel stresses by adopting equilibrium and compatibility method.

C$.$ Explain the reason for the differences between the two methods

$f_c^{\text{'}}=32$MPa,$E_c=30100$MPa,$E_s=200{10}^3$MPa;${}_{cs}^{***}=600{10}^{-6}$
