Not long ago a very thoughtful thread cleared my mind on the Relativity of Simultaneity. I am very thankful and hope to get here help also on a question related to the RELATIVITY OF MEASUREMENTS in the moving reference frames. Suppose that innumerous bars (or rods) are loaded on a very long standing still train and aligned with their length strictly along the railroads. Several ones are given to an observer on the station. All bars are made with exactly the same length. The train moves along a straight line and when the observer on the station measures, by an ingenious indirect method, the bars on the train he determines that the bars on the moving train are shorter than the ones he has on the station, the more so the faster the train moves, which is explained by the Special Relativity. The train stops and the observer on the station can now measure and compare the bars from the train with the ones on the station directly. What does he find? Are the train bars still shorter that the station ones or have they recovered their original length? Many thanks for attention.
