Question
Solve it :
The simply-supported beam above is subject to the loadings shown. The cross-section is uniform and is shown to the right. Complete the following: Calculate the maximum magnitude of the internal bending moment about the z-axis (Mx) due to the 12 kN point loads Determine the: Location of the neutral axis for bending about the z-axis (yNA) Moment of inertia about the z-axis (Iz) Location of the neutral axis for bending about the y-axis (zNA) Moment of inertia about the y-axis (Iy) Calculate the magnitude and show the location of the maximum compressive and tensile normal stresses on the cross-section due to the following: The maximum moment calculated in part (A), Mz A bending moment about the y-axis equal to My = +6 kN m Mz and My acting concurrently
