Two cylinders on a plane forming an angle

θ

with the horizontal have the same radius

r

and the same length

h

. The cylinders have densities

ρ

1

and

ρ

2

. They can be solid or have walls of thicknesses

e

1

and

e

2

. You can adjust the densities or thicknesses to get the same mass for both cylinders. Now use the time control to roll the cylinders down the plane and observe what happens.
