Chapter 7, Problem 7.15(choose chapter or problem)
Under certain conditions, wind blowing past a rectangularspeed limit sign can cause the sign to oscillate with a frequency. (See Fig. P7.15 and Video V9.9.) Assume that is a functionof the sign width, b, sign height, h, wind velocity, V, air density, ,and an elastic constant, k, for the supporting pole. The constant, k,has dimensions of FL. Develop a suitable set of pi terms for thisproblem.
