a lever with an output arm of 0.8 has a mechanical advantage of 6. What is the length of the input arm?

OpenStudy (anonymous):

Mechanical advantage = output force / input force M.A. = input distance/ output distance 6 = input distance / 0.8 input distance = 4.8 giving a lever arm ratio of 4.8/0.8= 6.
