1. Check the tabulated moment of inertia for a 300×610 nominal-size timber cross section
2. For the cross section of Problem 8.3, calculate the moment of inertia with respect to the Y-Y centroidal axis
Problem 8.3
A structural steel wide-flange section is reinforced with two steel plates attached to the web of the member, as shown. Calculate the moment of inertia of the built-up member with respect to the X-X centroidal axis.
