WebMoment of inertia is a different concept. This is about how easy it is to turn a body based on its mass and the distribution of the mass. so, if you have a mass of 20kg attached to your door near the hinge and you push the … WebApr 24, 2024 · Proof. We simply calculate the moment of inertia around the z-axis (where A is the area of the object, and σ the mass per unit area): (5.4.10) I z = ∫ A ( x 2 + y 2) σ d A = ∫ A x 2 σ d A + ∫ A y 2 σ d A = I y + I x. Note that the last two lines of Table 5.1 (moments of inertia of a thin planar rectangle) satisfy the parallel axis ...
