Figure 5. The vertical rail (black) and the diagonal rod (green) are differently positioned to each one’s direction of motion (black vectors) in the observer’s frame ). Consequently, they differently react to Lorentz contraction along these directions: the rod changes its diagonal position (from green to the red one). As a result, it adheres to the rail whose perpendicular position remains unchanged. Like in the previous version, this means incompatibility between observations made in the rail and rod frames (deviation from the rail) and in the observer’s frame (adherence). Green vector indicates direction of the rod’s motion observed in the rail frame
