If you are referring to the "velocity ratio", which I admit I have never seen in a "lever problem" before, since the load arm is 6 times as long as the effort arm, the load will move 6 times as far as the effort in the same amount of time and so will have 6 times the velocity.
problems, velocity ratio= distance move by effort / distance move by load, trouble is there is no indication of any movement that i can see,
also if i use force ratio / efficiency x 100. no machines are ever 100%
A lever changes
should i have worked out a new applied effort from 3000j if so can somebody guide me on this,
