Discuss Concept Problem 1 1. A mass M is horizontally attached to a spring with a spring constant k. Let's consider two different inputs: a) A sudden step force Fo in the downward direction. Analyze the resulting motion, like amplitude and mean value. Now include a damper: How can you find an engineering characterization of a "Damper"? What will the final displacement be, whern including the damper? (System at rest) . b) An oscillatory force F A sin(wt) will be applied. Perform the same analysis as in a), but exclude the damper. Explain what "Resonance" means. Find "real world" engineering applications (or engineering disasters) induced by resonances
