2. calculate the second moment of area of each of the sections shown below about an axis X-X through the centroid. If the beam section is subjected to a bending moment MK Nm acting in the sense shown. If the maximum tensile and compressive stresses are limited to 30 M N/m² and 45 M N/m², respectively, calculate the maximum allowable value of M. 60 10 mm 130 mm ... 5% point will be deducted from the student's mark for that assignment. 5% mark will be lost for each day up to 10 days that the assignment is outstanding. Any assignment received after the first ten days but up to the three weeks after the stated deadline will see a 50% points deducted.
