PROBLEM 9.109 It is known that for a given area 4 300 in y I = and 4 125 in xy I =− , where the x and y axes are rectangular centroidal axes. If the axis corresponding to the maximum product of inertia is obtained by rotating the x axis o 67.5 counterclockwise about C , use Mohr’s circle to determine ( a ) the moment of inertia x I of the area, ( b ) the principal centroidal moments of inertia. SOLUTION First assume x y I I > (Note: Assuming x y I I < is not consistent with the requirement that the axis corresponding to the () max xy I is obtained by rotating the
