Why are board pins made with one end Broad and other end Sharp?
one end of drawing pin is kept sharp
so that it can Pierce the drawing board as more pressure will be applied since pressure is inversely proportional to area.
Why does a drawing pin have a broad top and pointed lower end?
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 one end of drawing pin kept wide but the other end very sharp?
In a drawing pin, one end is kept wide while the other end is very sharp . It is because
while piercing a drawing pin, one has to apply some external force on the up side of the pin so that it gets pierced
. In order to apply more force the head has to be wide .
Why has a drawing pin a board head and a pointed tip?
Why does a board PIN have a sharp tip? The
tip of pin is sharp to have ease in penetrating it
. It is made thiner and sharper so that it acquire less area so that amount of force is required is minimised. Exactly opposite at other at head to prevent it from penetration.
Why are drawing pins so easy to push into a surface?
Drawing pins
have a large round end for your thumb to push
. The round end has a large area, so it exerts a low pressure to your thumb. The sharp end has a very small area. The same pushing force produces a high pressure there, so it pushes into the notice board.
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 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 tip of the pin is sharp but the head is broad?
The tip of pin is sharp
to have ease in penetrating it
. It is made thiner and sharper so that it acquire less area so that amount of force is required is minimised. Exactly opposite at other at head to prevent it from penetration. … Hence lesser the area lesser the force required for penetration.
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 are board pins made sharp?
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.
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 .
Does pressure exerted by a liquid increase or decrease with depth?
Pressure increases as the depth increases
. The pressure in a liquid is due to the weight of the column of water above. Since the particles in a liquid are tightly packed, this pressure acts in all directions.
The force per unit area is pressure. The force on the object is spread over the surface area
. The area where the force is applied is divided by the equation for pressure.
What are the factors on which the pressure exerted by a body depends?
As such, pressure depends on
the amount of gas (in number of molecules), its temperature, and the volume of the container
.
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 syringe and needles have pointed ends?
Why do we make needles sharp and pointed? When a needle is pushed against a surface,
the end of pin exerts some pressure on the surface
. A sharp pointed end has a very small surface area to be in contact with, due to which pressure becomes very large at that point. This helps in easier working with needle.
