1. The problem statement, all variables and given/known data What is the angle of twist at gear A relative to the motor? (Round to the closest 6th decimal) 2. Relevant equations I know to find the angle its θ = ∑ (TL/JG) but it can also be θ = Lτ/Gr 3. The attempt at a solution So i used both these equations, and I got (-29.18*0.052)/(1.57x10^-8 * 83x10^9) = -1.163833x10^-3 rad, which was the same result for the other one too. However, this was wrong and I'm not sure what I am doing wrong?
