Easy to install the door handle:
The principle of the door handle is the principle of leverage. The fixed point on the wall is the fulcrum, and the handle force is used as the point. The lever has three points: force point, fulcrum and resistance point.
It saves effort when the distance from the point of force to the fulcrum is greater than the distance from the resistance point to the fulcrum; when the distance from the force point to the fulcrum is equal to the distance from the resistance point to the fulcrum, no effort is saved or effortless; when the distance from the force point to the fulcrum is less than the distance from the resistance point to the fulcrum Laborious.
