"A 100% rigid…" doesn't exist. The pressure wave you are proposing will propogate through the rod at the rod's speed of sound. In extreme rigidities, we can look at the fact that the rod is held together by electromagnetic forces and specify the theoretical limit for electromagnetic propagation (c). Since no material provides a speed of sound anywhere near the same magnitude as c, we won't worry about it. ../greg
