1. The problem statement, all variables and given/known data Calculate the velocity ratio of the system. Third Class Lever Efficiency = 65% Mechanical Advantage = 1/6 Work Put In 3000J (I know if the system was theoretically 100% efficient the velocity ratio is 1/6 or 0.167) 2. Relevant equations Velocity Ratio = Mechanical Advantage / Efficiency 3. The attempt at a solution VR = MA / E VR = 0.167 / 0.65 VR = 0.257 This to me is a confusing answer as of the system was 100% efficient the ratio is only 0.167 and calculating it on 65% i'm getting a larger velocity ratio this can not be correct can it? Could someone please point me in the right direction?
