Here is a simple question.
How can an observer measure length (or length contraction) of a cylindrical Iron rod, when it is moving with a relative velocity v with respect to the observer?
The reason to ask is not to inquire the math about it, but if the rod is moving say in x direction, from the observer's point of view, he will se only a circle (cross section of the rod in yz plane)!, assuming the observer is at the origin of the stationary frame, or at least on x axis.
(I think, If observer is not on x axis, and the rod is moving in x direction, the rod is not moving with uniform relative velocity with respect to the observer)
Edit: The length of the road is parallel to (infect coinciding with) x axis.
