Hi, I want to clear my concept about the direction of torque for a sin curve. Assume the torque can be represented by a sin wave (T=sinx, where x is from 0 to 2π and it starts from the origin(0,0) with an amplitude of 1. My understanding of the torque direction is as follows (assumuing clockwise torqe to be positive): 1- from 0 to the first maxima (0≤T≤1), torque was increasing and its direction was positive. 2- from first maxima, the direciton of the torque becomes anticlockwise until it reashces the first minima. (i.e. for 1≤T≤-1 torque is anti-clockwise) 3- From the first minima until the zero crossing, the direction of the torque becomes clockwise again.i.e. (-1≤T≤1, torque is clockwise again). Please comment if I am right or wrong and suggest me the true direction sense for this particular case. Many thanks for your help!
