PROBLEM 9.148 Aluminum wire with a mass per unit length of 0.049 kg/m is used to form the circle and the straight members of the figure shown. Determine the mass moment of inertia of the assembly with respect to each of the coordinate axes. SOLUTION First compute the mass of each component. Have mL ρ = Then ( ) ( ) 1 0.049 kg/m 2 0.32 m m 0.09852 kg = 2345 = == mmmm ( )( ) 0.049kg/m 0.160m 0.00784kg Using the equation given above and the parallel axis theorem, have () ( ) ( ) ( ) 1235 xx x x x I IIII =+++ ( ) 22 11 0.09852kg 0.32 m 0.00784kg 0.160m
