Problem 1 For the beam cross-section shown in the figure below, find the cracking moment. - Assume the applied load produce a positive moment on the section (i.e. counterclockwise). - Use \( f_{c}^{\prime}=4 \mathrm{ksi} \) (or \( 4000 \mathrm{psi} \) ), \( f_{r}=7.5 \lambda \sqrt{f_{c}^{\prime}} \), normal-weight concrete.
