A unmounted tire has a wall with a radius of 34 cm and a width of 24 cm. The rubber on the walls have a thickness of 0.99 cm. The width of the tire is 20 cm, and the tread thickness is 1.8 cm. The rubber the tire is made of has a density of 1.83 g/cm3. This tutorial will work through finding the moment of inertia of the tire as it rolls, which includes first finding the mass of the tire. Finding the mass of the tire, itself, exemplifies the piecemeal way in which we construct the moment of inertia in this situation. Wall Thickness Part 3 of 5 - Volumes It will be helpful to calculate the volumes of the walls and the tread first, so let's do that. Both the walls and the tread have the same shape: a hollow cylinder of finite thickness. 50, if you will, please calculate the volume of both a single wall and the tread. (a) The volume of a wall: vw=_x (b) The volume of the tread: V. = 2371.64 cm' x
