Review Exercise: Second Moment of Area

Course subject(s) 4. Bending Moment in Beams

In this course, you are expected to be able to calculate the second moment of area, I, for a cross section. This value is required in the flexure formula for relating normal stresses to internal bending moments. If needed, please review your statics notes to refresh your memory on calculating I. The problem should help you assess your ability to calculate second moments of area.

Second Moment of Area for a C-Channel Section

For the cross-section given below, prove that the second moment of area is equal to: I = 2.47 x 106 mm4
