  • The machine works as a force multiplier when the effort required by that machine is less than the load i.e MA>1.
  • The machine gives a gain in speed if that machine needs effort greater than the load i.e MA<1.
  • The machine is used to change the direction of the effort when the load and required effort are equal i.e MA=1
