Thin wall approximation moment of inertia
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 door … WebMoment of Inertia: Rod. Calculating the moment of inertia of a rod about its center of mass is a good example of the need for calculus to deal with the properties of continuous mass distributions. The moment of inertia of a point mass is given by I = mr 2, but the rod would have to be considered to be an infinite number of point masses, and each must be …
