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.
How does a bobby pin suspend in honey?
A bobby pin can suspend in honey due to the honey's high viscosity creating resistance to the pin's movement through it. The honey's sticky properties also help to adhere the bobby pin to the surrounding honey molecules.
Why did Edwin Moore invent the push pin?
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.
Why does that a small pin sinks in water?
The pin sinks in water because its density is greater than that of water. This means that the weight of the pin is more than the amount of water it displaces, causing it to sink.
Why is it easier to push a sharp pin into a board rather then a blunt pin?
A sharp pin has a smaller surface area, which means that the force exerted by the sharp tip is concentrated in a smaller area, making it easier to penetrate the board. In contrast, a blunt pin has a larger surface area, so the force is spread out over a larger area, making it harder to penetrate the board.
