Question

Explain the various functions that a machine can perform.

✓

Answer

Various functions that a machine can perform are :

Changing the direction of applied force – Example : When a flag is hoisted with the help of a pulley.
Changing the magnitude of applied force – Example : Bottle opener multiplies the applied force and much less effort is required to open the cap.
Applying force at a convenient point – Example : In a pair . of scissors, the input force is applied at the handle of the scissors which cuts the paper at the other end of the blade.
Changing the speed of an object – Example : While riding a bicycle, force is applied on pedals which multiplies the speed.
