1. The problem statement, all variables and given/known data I need to solve a problem where a 7.5 Kg object is attached to an ankle and leg lifts are done. There is a picture that shows the leg being at rest where the angle is 0, then legs its lift to 30 degree angle, 60 and 90 degree angle I am suppose to find the torque about the knee due to this weight for the 4 positions (each angle) 2. Relevant equations torque = rF sin (angle) 3. The attempt at a solution So i used the equaiton above to solve this problem which gave me at 0 degrees = 0 N.m at 30 degrees = 15 N.m at 60 degrees = 25 N.m at 90 degrees = 30 N.m is this right????
