What is mechanical advantages

 

 

• Mechanical Advantage is the ratio of load to the effort applied on that load.
• In other words, it indicates how the subjected load is divided by the effect of effort on it.
• 
• 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
