Solution
Moment of inertia is nothing but second moment of area and is the indicator of flexural stiffness
of the member.
In given problem, Moment of Inertia (MI) = BD3/12-(bd3/12)
= 10*113/12-(2*3.5*53/12) = 1109.16 -72.9 = 1036.2 in4. (about strong axis as the member is
symmetrical about XX or strong axis.
Now MI about weak axis, YY axis or vertical axis
(11*103/12)-(5*73/12) = 916.67-142.91 = 773.75 in4
Hightlighted values are the answers for the MI of strong and weak, ie horizontal and vertical axis
respectively..
