angular momentum

answered-by-expert Expert Answer
Yes, the law of conservation of angular momentum is involved in balancing a bicycle.
 
When a bicycle is moving, the spinning wheels have angular momentum. Unless there is some external torque or force acting to change their angular momentum, the angular momentum of the wheels remains constant. Hence, it obeys the law of conservation of angular momentum.
 
Also, the direction angular momentum of the bicycle wheels tends to remain constant. Hence, it takes a significant amount of external torque or force to change the direction that the wheels are spinning. Hence, the bicycle does not tip over easily and is easy to keep balanced.
 
When the bicycle is not moving and the wheels are not spinning, the wheels have zero angular momentum. It is therefore easy to change the direction that the wheels are spinning, and so balancing the bicycle is very difficult.

A Uniform Disc of diameter R/2 is put over another uniform disc of radius R of same thickness and Density. The peripheries of the two discs touch each other. The Centre of Mass of the system from centre of the big disc is? (I asked this question before but the answer was wrong. They took the Radius as R/2 while it is the Diameter)
