Question

Why is it difficult to close the door by applying force at the hinges?

Answer 1

Becoz the perpendicular distance from the hinges to the point where effort is applied ,is small,so it is difficult to close the door.

Answer 2

since, torque=force × perpendicular distance......................

so, when we are applying force at the hinges of the door, we are getting less torque for rotating the door around its axis......
