Mechanical advantage in physics and engineering refers to the rate of efficiency and speed a machine has on the work you are doing, thus the higher the mechanical advantage the easier the work is done.
A mechanical advantage is the force ratio that is produced by a machine against the force that is applied used in accessing the machine performance. It is calculated by dividing the output force with the input force; therefore mechanical advantage =output force/ input force.
Mechanical advantage is the benefit that is derived by using a machine(simple or complex) to help you do work. Because of mechanical advantage it is easier to push something up a ramp then to lift the same object all at once.
