The cross-section of two angles attached together are shown on the left below. The properties of angles are given in the table with reference to the diagram on the right. The maximum moment applied to the beam will be 10 kN-m. The double angle can be oriented such that the moment is applied around axis 1 or 2. Note the spacer block does not contribute to the 2nd moment of area (I) for the double angle con?guration. Determine the maximum stress for
a. Moment around axis 1.
b. Moment around axis 2.
