A push pin is a type of inclined plane, where the sharp end acts as the wedge. By applying force to the head of the pin, the sharp end easily penetrates into surfaces.
A board pin is a type of fastener and can be considered a type of simple machine known as a wedge. The pointed end of the pin helps it exert force to push materials apart, making it easier to fasten objects together.
A pin is classified as a type of fastener and not a simple machine. It is often used to secure two materials together.
Edwin Moore invented the push pin in 1900 as a way to securely attach papers together without causing damage. The design of the push pin allowed it to easily pierce through paper and hold it in place, making it a convenient alternative to traditional pins or clips.
A clothespin is considered a double lever simple machine. It consists of two rods (levers) hinged together to grip an object when squeezed.
Pressure is inversely proportional to area. A sharp pin has lesser area compared to a blunt pin. Therefore we require lesser pressure to push the pin with lesser area.Hence it's easier to push a sharp pin which has lesser area.

A push pin is a fastener. As a minimum, it fastens a very visible head to a surface. Even used symbolically on e.g. Google maps. Alternately it may fasten one surface (paper) to another.
The safety pin has a pin that goes into the head of the pin, and you push the point in or out of the head of the pin.

first push the pin to view trip miles. then to reset to zero push and hold the pin until you see zeros.
yes it has them.
