Hey, I was wondering about a scenario, perhaps you can help me. Imagine a bell hung from an arbitrary pole in which the friction of the bell-pole junction is known. Assume this bell and pole are in a clean room of known atomospheric density and pressure. Orthogonal to the plane of the pole is an actuator that thrust outwards a rod which strikes the bell and rings it. You also know the force of the rod that strikes the bell and you know the bell's mass. My question is, upon using the actuating rod to strike and ring the bell, can physicists measure how much of the energy goes into producing the ringing sound and how much goes into swinging the bell? I know this scenario is very loose, but my intention is to understand just how much energy is lost to sound propogation vs. bell deflection. If someone can provide a rough estimate of the order of magnitude that would be nice. You know, something like, 0.0001% of the energy is radiated as sound while 99.9999% of the energy goes into deflecting the bell. Thanks.
