Example 6.2
The beam cross-section shown consists of two aluminum channels fastened to a steel plate. The moduli of elasticity are 206 GPa for steel and 68 GPa for the aluminum. The 50 mm deep channels have cross-sectional areas of 197mm2. The steel plate is 70 mm wide by 10 mm in thick. Use the y0 and z0 axes shown in order to determine the location of the m.w. centroid.
