The moments of inertia of each section are easily found in a handboo or from the !endor. "owe!er, as we saw in the section on moments of inertia for composite sections, we cannot algebraically add moments of inertia

1. Weigh the square mass to find the mass M and record in Table 1.1 2. Measure the distance from the axis of rotation to the center of the square mass and record this radius in Table 1.1. Part 2: Measurement of the Rotational Inertia Accounting for Friction Because the theory used to find the rotational inertia experimentally does not include List of moments of inertia From Wikipedia, the free encyclopedia The following is a list of moments of inertia. Mass moments of inertia have units of dimension mass Г— length2. It is the rotational analogue to mass. It should not be confused with the second moment of area (area moment of inertia), which is used in bending calculations. The
