In Unit number 5, we're going to talk about the product moment of inertia for a rectangular section at the CG. We want to prove that the product moment of inertia for rectangular section =0 The moment of intertia of the first point is i1 = 0 (as the distance from the axis is 0). Of the second point: i2 = m (L/2)^2 = mL^2/4. Of the third point: i3 = mL^2. The total moment of inertia is just their sum (as we could see in the video): I = i1 + i2 + i3 = 0 + mL^2/4 + mL^2 = 5mL^2/4 = 5ML^2/12 Explanation: Moment of Inertia: Moment of inertia is the moment of the first moment of an area or second moment of inertia about an axis. It is a property of the section of a structural member and is a measure of the resistance of the member against bending i.e. deflection or deformation due to bending.; Principal Axes and Principal Moment of Inertia Here's how to calculate area moment of inertia of a beam with a T cross-section. I show you how to find the centroid first and then how to use the centroid. MOMENT OF INERTIA OF FLYWHEEL Objective The objective of this experiment is to determine the relationship between the angular acceleration of flywheel and the torque producing the acceleration. Theory Considering a falling mass, Net force=mg-F Acceleration=a Hence ma=mg-ma F=m (g-a) Provided that a is much greater than g

The Moment of Inertia of an Ellipsoid rotating about the Axis1 or 2 calculator computes moment of inertia about axis 1 or axis 2, the (the shorter axes, b or c, in the picture) based on the mass, the length of a and b. INSTRUCTIONS: Choose units and enter the following: ( m) This is the mass of the ellipsoid. ( b) This is the length of axis 2
