Why is the one end of a drawing pin kept wide?

Why is the one end of a drawing pin kept wide?

With one end wide we can apply large force in a small area which helps the pin to pierce easily on the board with large pressure. Again due to the large with on one end, the pressure applied on this results to be small and hence we don’t injure ourselves.

Why does a drawing pin have a broad top and pointed lower end?

Answer: pressure is equal to force over area, therefore when you apply a force onto the broad side of the drawing pin, the same amount of force is applied to the wall on the small point.

Why is the head of a thumb pin is flat and broad?

Answer Expert Verified The pin sharp but head is broad because if we exerts more pressure then it vil easily penetrate but if we exerts less pres. on a blunt pin then it will not easily penetrate ..

Why is it easy to press on the broader side of the thumb pin?

in order to push the pin onto a board some external force is applied and this force is applied on the broad side so that no harm should take place on our fingers and the front part is sharp as the pin can get inserted into the board easily……

Why do drawing pins have wide heads?

A drawing pin has two basic components: the head, often made of plastic, metal or wood, and the body, usually made of steel or brass. The head is wide to distribute the force of pushing the pin in, allowing only the hands to be used.

Why do safety pins and drawing pins have narrow and sharp tips?

Ans: Safety pins & drawing pins have narrow & sharp tips because the smaller surface area of the tip causes a high pressure and therefore, makes it easier for these objects to pierce through a given material.

Why it is easier to push a sharp tipped pin than a blunt tipped pin into a board?

When a given force is applied, a sharp tip pin covers lesser area and exerts more pressure as P = F A P=\frac{F}{A} P=AF​. Therefore a sharp pin works better than a blunt pin.

Why does drawing pins have flattened heads?

The head is wide to distribute the force of pushing the pin in, allowing only the hands to be used. Some drawing pin designs have a portion cut out of the head and bent downward to produce a pin.

Why do drawing pins have flattened heads?

Why is it easier to push a drawing pin having pointed tip than a pin having blunt tip?

Force and Pressure | Short/Long Answer Questions Q22) A sharp pin works better than a blunt pin. When a given force is applied, a sharp tip pin covers lesser area and exerts more pressure as P = F A P=\frac{F}{A} P=AF​. Therefore a sharp pin works better than a blunt pin.

Why is the tip of a pin very sharp?

Since the pressure is inversely proportional to the area of contact, so the pressure will increase. Thus, for increasing the pressure for a given force applied by us to drive the pin inside the sheet or paper, the tip of the all-pin is made sharp.

Why the edge of drawing pin is sharp and pointed?

Answer: one end of a drawing pin is sharp in order to increase pressure on the surface where the pin is to be inserted . So, that it easily pierce because smaller the area more the pressure will be exerted .

Why do pins and nails have sharp and pointed ends?

Pressure is the total force per unit area.The ends of the nails and pins are made sharp in order to minimize the area which in turn increases the pressure.So when you hit the nail on its head , even a small force converts into a large pressure due to the small area of the tail and the nail is able to insert in the wall.
