Chapter 10 295 P10.24 Treat the tire as consisting of three parts. The two sidewalls are each treated as a hollow cylinder of inner radius 16.5 cm, outer radius 30.5 cm, and height 0.635 cm. The tread region is treated as a hollow cylinder of inner radius 30.5 cm, outer radius 33.0 cm, and height 20.0 cm. Use Im R R =+ 1 2 1 2 2 2 ej for the moment of inertia of a hollow cylinder.
