Parajumble Question: 16 The dumbbell vibrates when it is linear and spins when it is circular and is activated by a laser which can work in a straight line or a circle. A spinning dumbbell functions as a rotor, and a vibrating dumbbell tasks like a torsion balance. The machine spins at more than 60 billion revolutions per minute, which is more than 100,000 times faster than a high-speed dental drill. The team synthesized a tiny dumbbell from silica at Purdue University in the US and then levitated in a high vacuum using a laser. The fastest human-made rotor in the world developed by Scientists will help study quantum mechanics.
