Is anyone able to answer these questions!

What is the length of the coordinates in the two inertial systems S and S' at the velocity *v*, according to relativity - if the length of the coordinates are identical at *v* = zero?

1) Is the physical length of the coordinates greatest in S?

2) Is the physical length of the coordinates greatest in S'?

3) Is the physical length of the coordinates in S equal to the physical length of the coordinates in S'?

If the physical lengths are identical, will it then be possible to have any physical length contractions according to relativity? Or, in other words, have you ever experienced a length contraction because of the movement of another coordinate system?

If it isn't possible to have any length contractions according to relativity, how can relativity then explain the relativistic experiments where a Lorentz contraction occurs?
