You have been assigned as designer for a 1 mm thin steel plate of density 7850 kg/m3, to be used in a machine element. The technical graphics department provides you with a cross section of the plate shown in Figure 3. You are requested to compute the minimum possible mass moment of inertia about the given axes, to submit to the next engineer to fabricate the element accordingly.
