Why is it easy to hammer a nail into the wood but not a bolt?
Answer Expert Verified Nail has a pointed end while a screw (bolt) has a blunt end. As surface area decreases, pressure increases. Since nail has less surface area when compared with a screw, it is easier to drive a nail into wood as pressure is more.
What happens when you hammer a nail into a wood?
Explanation: If you properly time your hammer strikes, the last blow will drive the nail head slightly below the surface of the material you’re nailing into. Done properly, the shape of the hammer head will slightly countersink the nail but will not mar the wood surface at all.
Why is it possible to drive a nail into a piece of wood?
First, there’s the issue of acceleration. Hammers are very hard and solid, so when you hit the nail head with the hammer, the energy and force of the blow is delivered at almost an instant. Third, hammers work as an additional lever, allowing you to deliver more force as a trade-off with time.
Why does the nail exert more pressure on the wood than the hammer?
Answer Expert Verified 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.
Why is hammering the pointed end of a nail into wood easier compared to the flat end of the nail?
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.
When a hammer hits a nail what force makes the nail dig into the wood?
A hammer hits a nail, driving the nail downwards into a piece of wood. The “reaction” is the force of the nail pushing upwards on the hammer, which stops the hammer. You are standing on the floor. The floor is pushing up on you (holding you up against gravity).
What makes the hammer stop when it hits the nail?
A hammer hits a nail, driving the nail downwards into a piece of wood. The “reaction” is the force of the nail pushing upwards on the hammer, which stops the hammer.
Why is it difficult to drive a nail into a block without holding it?
Why is it difficult to drive a nail into a wooden block without supporting it? Answer: When we hit the nail with a hammer, the nail and unsupported block together move forward as an single system. There is no force of reaction.
Why did the nail goes deeper and deeper into the wood?
You only need protection against the “equal and opposite reaction” of the nail against your soft hands. The nail can penetrate the wood because it is sharp, applying high pressure to the surface area it contacts.
Why is a nail pointed?
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.
