Homework Statement
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)
Homework Equations
Velocity Ratio = Mechanical Advantage / Efficiency
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?
