Why bows get stiffer and racquets get softer when the strings are added
نویسنده
چکیده
The frame of a string instrument is subject to a large tension force when the strings are installed. Intuitively, one might expect that the frame would be stiffened by the strings. Experimental data and a theoretical analysis are presented to show that this is not generally the case. An archer’s bow is much stiffer when it is strung, but a tennis racquet is softened when the strings are added. As a result, the mode frequencies for transverse vibrations increase for a bow and decrease for a racquet when the strings are added. The effect of the strings depends on the extent to which the frame is bent at equilibrium. © 2001 American Association of Physics Teachers. @DOI: 10.1119/1.1376378#

متن کاملBinary Strings and Graphs
Binary strings of length n can be added and permuted. Of special interest is the permutation that cyclicly shifts a binary string to the right. For example, when n = 5, then cyclicly shifting 10110 to the right yields 01011. Obviously if we cyclicly shift a string of length n to the right n times to get back what we started with. Addition of the strings is done component-wise modulo 2. For inst...
