Reply to comment by OverJohn in If an object is placed at the end of of a VERY long bar that is connected to an axel, Could rotating the bar close to the axel make the object at the other move extremely fast (like light speed)? by Swade060504
In classical mechanics, if the stiffness (ie the relevant elastic moduli for the wave type) tends to infinity or the density tends to zero then the speed of sound tends to infinity. Am I correct to think that when you apply special relativity, the speed of sound would tend to c and not infinity in those limits?
