Assume the section has cracked and use the transformed-area method to compute the required parameters for the beam shown.

Solve for:

1.) The value of x from locating the neutral axis using Qtop=Qbot in mm

2.) The value of the moment of inertia in mm4

3.) The compressive bending stress on concrete in MPa

4.) The tensile bending stress on the tension bars in MPa

5.) The compressive bending stress on steel in MPa
