Abstract:A discussed problem has been proposed, which is on a famous book,“Vibration Problems in Engineering”, written by Timoshenko S. The problem is that the equation(equation 1.77e, p.135) in original Chapter 1 passage 15 is wrong. A revised conclusion in theory has been inferred tightly. After dimension analyzing and study on exercise answer, the equation’s dimension has been proved to be inconsistent and not a printing mistake. The revised conclusion has theoretical meaning in vibration and practical significance in engineering computing.
Key words: vibation problems engineering controvertible problem
