BIO 235 Assignment 2 Questions and Answers 100% Pass With regards to effort and load, describe the main difference between a lever operating with a mechanical advantage versus a lever operating at a mechanical disadvantage. - Answer- a. Mechanical advantage- If the load is closer to the fulcrum and the effort farther from the fulcrum, then only a relatively small effort is required to move a large load over a small distance.Mechanical disadvantage- If the load is farther from the fulcrum ...
