Why is nail pointed tip?
Why is nail pointed tip?
The tip of a nail is sharp and pointed because the area under the pointed end of the sharp nail is very small. Therefore, the pressure exerted by a sharp nail is more on the wall and it can pierce easily on the wall with less amount of work done.
What happened when the pointed end of the iron nail get nearer to the small metal pins?
What happened when the pointed end of the iron nail got nearer to the small metallic pins? it attracts the small metallic pins.
Why are nails made very sharp at one end and thicker at the other end?
why are nails made very thinat one end and somewhat thick at the other ? This happens because pressure is inversely proportional to area, so when area is decreased more pressure is exerted which makes the penetration of nail easy.
What is pressure Why edge of nails are made sharp and thin?
1)nails are thin or pointed at the end so that the area of contact force become very less increasing the pressure because pressure is inversely proportional to the area. hence with this relation the nail will easily penetrate .
Why do we fix a nail in a wooden plank at pointed end and not a flat end?
Ans: It is easy to push a nail into a wooden plank by pointed end because the smaller the area, larger the pressure on a surface for the same force. The area of the pointed end of the nail is much smaller than that of its head.
Why is it easier to hammer a nail with a pointed end?
Heya, It is easier to hammer a sharp nail than a blunt one into the wood. This is because blunt nail occupies more area than sharped nail. As pressure exerted it inversely proportional to area lesser the the area, the pressure will be more.So the sharp will exert more pressure as it occupies less area.
What happens when a permanent magnet is kept in contact with an iron nail for many days?
What happens when a permanent magnet is kept in contact with an iron nail for many days? Ans: …… it becomes a magnet for some time i.e it becomes a temporary magnet even after removing a permanent magnet.
Why are board pins made sharp class 8?
Answer: Board pins are made sharp as they can easily penetrate the surface of the soft board .
Why is it easier to push a nail in a wooden plank?
It is easy to push a nail into a wooden plank by pointed end because the smaller the area, larger the pressure on a surface for the same force. The same force, therefore, produces a pressure sufficient to push the pointed end of the nail into the wooden plank.
Why does a sharp nail easily penetrate wood but not a blunt nail?
the sharp nail easily penetrate wood because more pressure is exerted in small unit contect area with wood but when blunt it’s area of contect with wood is more so pressure is distributed in some more are and the nail not cut .
Which nail is easier to hammer into the wood?
@ruchi: The reason is pressure. A blunt nail has more surface area than a sharp nail, so the pressure applied is less.
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.
Why are iron nails not magnetized to metal?
In step 1, when you tested the nail to see if it was a magnet, you realized it was not because it did not attract the metal in the paper clip. However, iron nails can be magnetized. Your compass did not react to the wire because the wire by itself emitted no magnetic field.
Why does my compass not react to iron nails?
What happened, and why! In step 1, when you tested the nail to see if it was a magnet, you realized it was not because it did not attract the metal in the paper clip. However, iron nails can be magnetized. Your compass did not react to the wire because the wire by itself emitted no magnetic field.
What kind of nails are used to fasten wood?
Nails are most commonly used to fasten pieces of wood together, but they are also used with plastic, drywall, masonry, and concrete. Nails are usually made of steel but can also be made of stainless steel , iron, copper, aluminum, or bronze .

What kind of nail is used as a fastener?
In woodworking and construction, a nail is a pin-shaped object of metal (or wood, called a tree nail or “trunnel”) which is used as a fastener, as a peg to hang something, or sometimes as a decoration. Generally, nails have a sharp point on one end and a flattened head on the other, but headless nails are available.
