Ideal Mechanical Advantage (I.M.A.) – The ratio of the total load to the effort is called Ideal Mechanical Advantage (I.M.A.) Therefore, I.M.A. =Total load/effort. [ the total load is the sum of the force to overcome the moveable parts, load due to friction, and the useful load.]Actual Mechanical Advantage (A.M.A.) – The ratio of useful […]
