I have a 4-way cross/medal that I was told is the combination of a miraculous medal and the brown scapular.
A Ferris wheel moves from a gravitational force which moves the axle, thus, making the wheel rotate swiftly. 2 people found this useful.
The heat from the rotor transfers to the wheel and they get real hot. Brakes work by converting kinetic energy to heat energy, absorbing and dissipating the heat energy is a function of the brake system which is partly done by the wheel.
