hello,

Please see attached Ex and its Answer. I'm surprised that the pressure Txx has the same value as that in the instantaneous frame of the rotating rod Tx'x'. I believe this could be a typo isn't it ?

Isn't the Lorentz transform the following matrix for the rotating rod around the z axis ?

1 0 0 0

0 sqrt(1-v*v) v 0

0 -v sqrt(1-v*v) 0

0 0 0 1

where v = aw

thanks,
