WebJul 20, 2024 · In the first integral in Equation (16.A.8), r S, ⊥, c m = d S, c m is the distance between the parallel axes and is a constant. Therefore we can rewrite the integral as. d S, c m 2 ∫ b o d y d m = m d S, c m 2. The second term in Equation (16.A.8) is the moment of inertia about the axis through the center of mass, WebMechanical Engineering questions and answers. 2. (25pts) Coordinate system is (0,0) at top center. Using the parallel axis theorem, find the 2nd moments of the area Ixc and Iyc about the centroid at x=0 mm,y=−154 mm. Ignore the effect of the joining region between the three pieces. Use the table approach.
