4Explanationfor a lever,effort * effort arm = load *load armso by re arranging above equation,load/effort = effort arm/load armNow, as load/effort is called mechanical advantage so,mechanical advantage = effort arm/load armAs total length of rod is 2 m out of which 1.6 m is effort arm so remaining 0.4 m would be load arm. thus on putting values in the above equation, we getmechanical advantage = 1.6/0.4 = 4
