Answer 2

Answer:

It is difficult to open a door by pushing or pulling near the hinges because at the hinge the torque is zero.

Explanation:

• The turning effect of a force is known as torque and it is given by τ = r × F
• Pushing or pulling the door open at the hinges is always difficult because there is no distance between the axis of rotation and the point of application of force, and as a result, there is no torque.
• In order to make it simple to push or pull open and shut the door, the door handles are placed away from the hinge.
• With increasing distance, the rotational effect begins to increase. It's simpler to open a door if you grasp the knob and push closer to the hinges.
