When you open a door what force do you exert on it is there any work done?

When you open a door, you exert a force in the direction of the door's motion. This force creates torque, which causes the door to rotate around its hinges. Work is done when this force causes the door to move against resistance, such as friction between the door and the door frame.


How does electromagnets work in a automatic doors?

In automatic doors, an electromagnet is used to create a magnetic field that attracts or repels a metal plate on the door. When an electrical current is applied to the electromagnet, it generates a magnetic force that moves the metal plate, allowing the door to open or close automatically. This process is controlled by sensors that detect movement, ensuring the door operates efficiently.

How do spring hinge pins work in a door mechanism?

Spring hinge pins work in a door mechanism by using a spring-loaded design that helps the door close automatically. The spring inside the hinge pin provides tension, which helps the door swing shut when it is opened. This mechanism is commonly used in self-closing doors to ensure they close securely after being opened.
