Why do cylindrical objects like cans roll in a circular motion?
The can is not a cylinder, but is slightly tapered. Products such as aluminum drink cans are manufactured using a process that involves drawing the metal over a form. Drink cans are fairly sophisticated products, since they are designed to maximize strength while using the minimum amount of metal. If the sides of the form were parallel, it would be difficult to release the can from the form. This would increase the reject rate, slow production, and require more metal. Instead, the sides of the forms are tapered slightly to allow the drawn product to be removed more easily. ————————————————– Re: “lacks cited evidence” Ahh, the ratings rapist shows up to hand out bad ratings. It is unfortunate that you choose to demonstrate your ignorance of the physical and applied sciences in this manner.
