The ratio of load to effort is called mechanical advantage. Mathematically,  Mechanical advantage = load/effort Thus, MA depends upon load and effort. In addition, MA also depends upon friction as .....

The mechanical advantage of a machine is the ratio of the load (the resistance overcome by a machine) to the effort (the force applied). There is no unit for mechanical advantages since the unit for both .....

There is more or less friction on every machine.  So, there is a loss of input work on every machine.  That gives the output work always lesser than the input work.  You know that efficiency is the ratio of output work to the input .....
