WebOct 22, 2024 · First, we need to calculate the moment of the system (Equation 6.6.2 ): M = 4 ∑ i = 1mixi = − 60 + 15 + 60 − 45 = − 30. Now, to find the center of mass, we need the total mass of the system: m = 4 ∑ i = 1mi = 30 + 5 + 10 + 15 = 60kg Then we have (from Equation 6.6.3) ˉx– = M m = − 30 60 = − 1 2. Web(a) In the question, we have given a rectangular I shaped beam with different dimensions. We have to calculate the moment of inertia about the z-axis passing through the centroid. For this, let us redraw the figure as follows, by considering 3 rectangular blocks.
