Answers
The law of lifting machines is an equation that prescribes the relation between the load( to be lifted) and the effort( that is to be applied).
It is based on the principle of a lever ( which is a simple machine). It has a load, fulcrum and effort.
They operate by applying an effort at a particular point which helps in moving of lifting the load at another point by balancing at the fulcrum( pivot).
Answer:
The law of lifting machine is an equation that prescribes the relation between effort which is applied and load that is lifted. The law clearly indicates the principle of the lever (that is regarded as a simple machine).
It possesses a fulcrum, load and effort. They can operate by putting the effort at any particular point that helps to move the lifting of the load at any point by maintaining a balance at fulcrum.
