A 200-kg flywheel is at rest when a constant 300 N ??? m couple M is applied
Question:
A 200-kg flywheel is at rest when a constant 300 N ??? m couple M is applied at time t = 0. At t = 28s the flywheel reaches its rated speed of 2400 rpm and the couple is removed. Knowing that the radius of gyration of the flywheel is 400 mm, determine?
(a) The average magnitude of the couple due to kinetic friction in the bearing,?
(b) The time at which the flywheel comes to rest.

During the course of my study, I have worked as a private tutor. I have taught Maths and Physics to O'Level and A'Level students, as well as I have also taught basic engineering courses to my juniors in the university. Engineering intrigues me alot because it a world full of ideas. I have passionately taught students and this made me learn alot. Teaching algebra and basic calculus, from the very basics of it made me very patient. Therefore, I know many tricks to make your work easier for you. I believe that every student has a potential to work himself. I am just here to polish your skills. I am a bright student in my university. My juniors are always happy from me because I help in their assignments and they are never late.
