1. The problem statement, all variables and given/known data I am trying to solve 18-10 http://img845.imageshack.us/img845/7287/motorf.jpg [Broken] 2. Relevant equations P = Cω 3. The attempt at a solution P = Cω 1 HP = 746 w 2.4 HP → 1790.4 w C = P/ω = 1790.4 w / 40 rad/s C = 44.76 Nm I am really stuck with this problem, I don't know how to continue. Your help will be appreciated.
