Problem Solving Strategy 37.2: Length Contraction Learning Goal IDENTIFY the relevant concepts The concept of length contraction is used whenever the length of an object measured by observers in different inertial frames of reference is compared To practice Problem-Solving Strategy 37.2 Length Contraction SET UP the problem using the following steps A support crossbeam on a high speed train is made from a titanium rod that has a length of 0.650 m when 1. Decide what defines the length in question. If the problem statement describes an object such as a ruler, it is just the distance between the ends of the object. 2. Determine what the target variable is Figure EXECUTE the solution as follows 1. Determine the reference frame in which the object in question is at rest. In this frame, the length of the object is its proper length 2. Keep in mind that length contraction occurs only for lengths parallel to the direction of relative motion of the two frames. Any length that is perpendicular to the relative motion is the same in both frames crossbeam 3. Use the equation to relate l and lo, and then solve for the target variable EVALUATE your answer: Check that your answers make sense: I is never larger than lo and u is never greater than the speed of light c 3.00x108 m/s
