Here's the issue. I'm doing some research involving MEMs where we will be making micro-accelerometers using cantilever beams with a proof mass on the end. I want to design these beams to break at specific accelerations (2 G's, 5 G's, 10 G's etc.) and I'm not sure how to go about this. My thought was use these forces to find the moment on the end of the beam and then use Max Stress=Mc/I to find the other properties of the beam. Is this the correct equation for this situation? I'm also not sure what the stress that a beam breaks at is called (ultimate strength, yield stress?). Just some general info on how to work through this process would be great, I haven't had much luck on google.
