A thin metal disk of mass m=2. 00×10−3kg and radius r=2. 20cm is attached at its center to a long fiber. (figure 1)when the disk is turned from the relaxed state through a small angle θ, the torque exerted by the fiber on the disk is proportional to θ: τ=−kθ. The constant of proportionality k is called the "torsional constant" and is a property of the fiber.

Iwas in a argument about a certain class grade with my teacher. it was a ‘a-’when i felt that i deserved a ‘a’. i showed him (my teacher) why i felt i derserved so. i questioned what i got wrong and showed him what i learned. i look back to that teacher with nothing but love and support because that’s the class that i actually learned the most. the moral of the story is to see where the other person is coming from and what they have done. also, when in a conflict, never attack the persons character. this will just make the argument end poorly.
