Move over Jeff Bezos, this invention is about to make you the richest person in the world. You have just invented the OyOy (that's YoYo spelled backwards). It is the very latest in home safety and so easy to use! If your building is on fire, simply reach out and grab the cord on the OyOy and you will be lowered safely toward the ground at a low velocity. The OyOy has a total mass M = 107.0 kg and is shaped like a cylinder of radius R = 0.850 meters. The secret to the operation of the OyOy is its patented shaft whose radius is only r = 0.0875 meters. The cord is wound around the small shaft and this is the secret to your low velocity. Outer Radius = R Spindle Radius - Rotation-OyOy-Energy Mass = M
