When we look at a door, we should not look at it as a rectangular wooden piece. If it that was true we will not be able to open it We must Look at it as a rotating object Which is Rotating about a fixed axis hinged at one of its sides For entering a room, we first have to rotate the doorknob. And then You either push the door or pull it depending on the type of the hinge. If you remember what we learned in kinematics, the word push or pull represents Force We are applying the force on the handle of the door in order to rotate the door but in this case, the force alone is not responsible for the rotation. There is something else in action here It is the distance from the axis to the point at which we apply the force. this combination is known as Torque. As push or pull denotes force, twisting creates a torque which is the rotational equivalent of force. Torque causes rotational motion of that object about one or more axes that pass through its center of mass. It is denoted by the greek symbol TAU Mathematically, Torque about a point is defined as the vector product of position vector and the force-torque is a vector which is perpendicular to both the position vector and the force vector As a result, the torque is a vector, perpendicular to the plane defined by position vector and force. The direction of the torque is given by the right-hand thumb rule. To apply the right-hand rule, put the fingers of right hand along the position vector and bend them towards Force vector, the direction of thumb will give the direction of torque Thanks for watching Download Extraclass.com app: - Play Store: http://bit.ly/extraclassapp Follow us on our social media handles to stay updated.
