1.	Why is the M.A of levers expressed as the ratio of load distance to the effort distance?
Answer» The ratio of weight (load) lifted by a machine to the force(effort) applied on a machine is called the mechanical advantage of the machine. Greater the value of mechanical advantage of a machine, more easier is the work is done. Mathematically, M.A = load/effort OR M.A = W/P UNIT: It has no unit.
