What is the principle of the door handle
The principle of the door handle is the principle of lever, the fixed point on the wall is the fulcrum, the action point of the handle force. Leverage has three points: the force point, the fulcrum point and the resistance point.
When the distance from the force point to the fulcrum is greater than the distance from the resistance point to the fulcrum, it saves effort; when the distance from the force point to the fulcrum is equal to the distance from the resistance point to the fulcrum, it saves effort and effort; when the distance from the force point to the fulcrum is less than the distance from the resistance point to the fulcrum laborious.
The handle can be used to hold, manipulate or move mechanical equipment and cabinet equipment (mostly on the door), and it is convenient for door opening, handle, handrail and other metal handles. The lever principle is widely used in life, bringing people’s life. More effort and convenience.
