Question

c) In a discussion with fellow engineers about vibrations, someone states that every- thing that you need to know in vibration investigations can be calculated using Runge-Kutta numerical integration (Matlab ode45 or similar) of the governing differential Equation of Motion. How do you defend that statement? How do you refute that statement? (d) Briefly explain the steps, tools, and techniques that you would take to analytically investigate a vibrations problem. (e) Mechanical systems must usually operate over a range of conditions. Unfortu- nately, one or more resonance points may have to be passed through during sys tem startup to operating state or during system shutdown. How can this type of transitory resonance problem be addressed? What analytical tools could you use to convince someone of your approach?
