The original poster attempts to create a free body diagram of a pendulum at its maximum amplitude of 30 degrees. The discussion revolves around the interpretation of the diagram and the concepts of amplitude and period in the context of pendulum motion.
Some participants provide feedback on the diagram, with one confirming its correctness after reviewing the image. There is an ongoing exploration of the definitions related to amplitude and period, with multiple interpretations being considered.
Participants note potential confusion regarding the angle representation and the definition of amplitude, indicating a need for clarity on these concepts. The original poster's homework constraints are not explicitly detailed.
Right. The period is the time it takes for one complete cycle. If it starts out to the right at 30 degrees at t=0, then in one period it will have gone to equilibrium, moved to the left at 30 degrees, come back to equilibrium and then back to the starting point at 30 degrees to the right.-EquinoX- said:ok, and the period of this pendulum is basically the time it takes the position I move the pendulum 30 degrees away from the equilibrium then I release it and it goes back again to the same position right?
No, the angle shown is the correct amplitude.kevtimc said:I think your theta should be flipped to the bottom. Currently, your amplitude is 150^{o}.
