    • Pulley: Imagine raising a flag on a flagpole. The
                        pulley at the top helps lifts the flag easily by

                        pulling a rope down, instead of lifting the flag
                        straight up.

                                                           uses  a  wheel  and  axle.  When  you  turn  the
                                                           knob  (wheel),  the  axle  inside  moves  and

                                                           unlocks the door.

                     Definition of a Plier

                     A plier is a special tool that helps us hold, bend, or cut things. It has two
                     handles and two jaws that open and close. When we squeeze the handles,

                     the jaws come together to grip or move objects.

                     Concept of a Plier

                        • How it works: A plier works like a pair of scissors, but instead of cutting,

                        it grips things tightly. The two handles are connected by a pivot point,
                        which allows the jaws to open and close. When you squeeze the handles

                        together,  the  jaws move  closer,  making  it  easier  to  hold  and  blend
                        something.

                        • Where we use it: We use pliers in many places, like at home, in workshops

                        or even in the garden. They can help us pick up small items, twist wires,
                        or even pull-out nails.

                        • Why it is useful: Pliers are helpful because they give us a strong grip
                        on things. This makes it easier to do tasks that are too hard to do with

                        just our hands.

                                                                              Understanding the Working of Robot   17
