Designing spinning or rotating machines can be complex and generally requires a bit of calculus. However, we can look at some simplified cases and design a few pieces that can help you analyze the motion of spinning—or in the case of this chapter, rolling—objects. Here we will develop a simple, basic rolling cylinder with internal structures that you can adapt to look into the physics of this deceptively simple-appearing motion.
Rolling Motion
If a wheel is perched at the top of a hill, before it starts moving it has
