I have a Simple question,
What will happen when i rotate a Pencil about the axis AB as in fig.
A ---------------------------------------------B
|
|
|
C
Let,
* The Pencil be in outer space, away from any gravitational influence.
* The Pencil be two Ly.sec long.
'C' is a neutral observer who is equi-distant from observer A and observer B so that light from A and B will have to travel a dist. 'd ' before reaching C.
Let obs. A rotate the Pencil about the axis AB.
Qs) 1>Will obs. A be able to Rotate the axis AB?, since the Kinetic Energy generated at End A will take more than 2 Secs to travel to B because AB is two ly.sec long and nothing can travel faster than light.
2>What will obs. 'C' note down about the event at A and B and what will he conclude?. (Imagine You being observer 'C'.)
