PROBLEM 9.141 A 2-mm-thick piece of sheet steel is cut and bent into the machine component shown. Knowing that the density of steel is 7850 kg/m 3 , determine the moment of inertia of the component with respect to each of the coordinate axes. SOLUTION Have st st mV t A ρρ == Then ( ) 32 1 7850 kg/m 0.002 m 0.320 0.240 m m × × 1.20576 kg = ( ) 2 7850 kg/m 0.002 m 0.320 0.180 m m × × 0.90432 kg = 3 1 7850 kg/m 0.002 m 0.180 0.240 m 2 m  × × ×   0.33912 kg = () 2 3 4 7850 kg/m 0.002 m 0.100 m 2 m π × 0.24662 kg
