Before starting experiments of prototyping of mechanical oscillator, I wrote a Pre-Lab in order to clarify the purpose and method of experiments and perform experiments efficiently. I also figured out the plan of experiments in this quarter with this Pre-Lab. From now on, based off this Pre-Lab, I am going to perform series of experiments. In this past week, as a preparation for the experiment of prototyping of monostable beam, I modeled a monostable beam with CAD. Using this model, I am going to make the first prototype of monostable beam in next week.
