Why does a sharp axe cut through wood more easily than a blunt one?

Because the cutting edge has a smaller area when the blade is sharp so the pressure it can exert increased

Why does a blunt pin require more pressure than a sharp pin?
There is more surface area so the force is spread out more
Why edge of nail made sharp?
to cut through material more efficiently.
Why does a sharp knife cut better than a dull knife?
Bacause the Sharp Knife has greater pressure than a dull knife.it cuts better because it is sharper. the force exerted on it is greater than it would be if it was blunt.The area on the tip of the blade is small meaning the pressure exerted is all at the end of the tip making it easier to use. (the force on both knives is the same)!AnswerWhen we cut any vegetable or fruit with a sharp knife suface area will be less so force applied is more and pressure will also be more (force is directly proportional to pressure). Thus,vegetables or fruits are cutted more perfectly.AnswerIt depends a bit on what is being cut and why.Imagine trying to cut a tomato with something really blunt, like a ruler.It wouldn't cut, but rather crush its way through, leaving a considerable mess.The sharper the blade, the less crushing there is, and you get nicer, more useful parts from the cut.If you're trying to cut something that's stronger/harder than fruits and vegetables, then a blunt blade would need to be pushed a lot harder against the surface before it starts to cut. If you want to do a bit of wood carving, you might simply not be able to push hard enough to get any "bite" if the blade isn't sharp enough.Sharp knives cut better than dull knifes because sharp knifes have a thinner blade, leaving less area to cut.Sharp knives cut neatly, without crushing cells of the food. The sharper knives also prevent cutting fingers as pressure is evenly applied and no slippage happens,Pressure is force per unit area, sharpness implies lesser area (that makes the contact). Hence, in case of sharper blades we end up with greater pressure which helps us cut an object more effectively. You can relate high pressure to concentrated force. So, in case of sharper blades, this concentrated force weakens the surface more effectively and hence easily cuts through.because the blade is thinner and its easier to cut with a thinner blade than a wider blade, it all comes down to atoms and how many atoms wide the knife it, the fewer atoms wide the knife is, the easier it will be to slice through something with it.It's easier because a sharp knife will cut through more quickly and accurately, than a blunt knife will take longer and it won't cut very well.Because there is less surface area in contact and the force applied is being concentrated on the less area.The same reason that it's easier to cut an apple with a sharp knife that with a blunt knife because sharp knife is very sharp and it is easy to cut but with blunt knife it is very hardIt is said that a sharp knife is better, and safer, than a dull one because with a dull knife, you have to work very hard to cut and that usually means sawing away at whatever you are cutting. A dull knife is more likely to slip and cut you because it is not easy to cut with. A sharp knife will do the job in one swipe and not much movement.A sharp knife has a smaller edge than a blunt knife. When dealing with fracture or tearing, a smaller edge means cutting a smaller area. On a molecular scale this means breaking fewer bonds, and less energy to separate the object into pieces.The sharp edge is the thin edge. The thinness is important because it needs to be thin to get between the molecules to 'cut'. The blunt edge is too thick to do this.Because the knife is sharp.Why is this question categorized in baboons?If you apply 10 lbs of pressure on a blunt knife, the pressure's spread over the area of the knife which is in contact with the meat, where as the sharp knife has a much smaller area, making the same pressure localised, allowing cutting to be done much easier.Maybe because its sharpcuz.A sharp knife has a smaller area on the edge of the blade, so you get a higher pressure with an equal amount of force. This means you can puncture the skin of a fruit with less force if you use a sharp knife.
Which has more force a blunt stick or a pointed stick?
If the stick is just sitting there, it doesn't exert any force at all. If you're swinging the stick, the shape of the stick won't matter much; the force will be determined by the speed and mass of the stick. If you are poking with the stick, then the FORCE will be the same whether it is blunt or pointed - but a pointed stick will concentrate the force into a smaller AREA, so the force per area will be a lot higher with a sharp stick than with a blunt one.
Why does hard objects reflect sound?
It reflects sound because sound can not travel through rubber as its got air bubbles in, and sound can not travel though gas as easily as it can travel through liquid, so its more easily reflected of rubber.
Why is tip of needle is made Sharp?
It's sharp - to help it pass through material without causing much damage. A sharp needle will only leave a tiny hole - while a blunt one might tear the fabric.
Why are blunt weapons favored over sharp ones when confronting hordes of zombies?
Blunt weapons have more force, whereas sharp weapons channel the force into a tiny point. Also, Sharp weapons have a nasty habit of stickeing in the zombie...
Why are blunt tools considered to be more dangerous then sharp ones?
It is more dangerous like you could injure yourself
Why does a blunt pin require more pressure than a sharp pin?
There is more surface area so the force is spread out more
Why do blunt knives make onions sting more than sharp knives?
You are crushing the onion not slicing it releasing more of the oils.
Why is a blunt edge more dangerous than a sharp knife?
"The sharp knife goes where you send it, the dull knife goes where it wants" is a reminder to keep your edges sharp. The dull blade is deflected by a hard material.
Why is it painful to walk on road with pebbles having sharp edges?
as the surface area is less i.e. the lesser the surface area the more is the pressure. an example is that an apple is easier to cut with the knife that has a sharp tip than a blunt knife
Why people make guns to harm people?
Because it's simpler and more efficient that using the blunt or sharp objects that people have been using for thousands of years.
Are leather seat covers more durable then cloth?

Why are the dull knives more dangerous than the sharp knives?
they will make a ragged cut which will get more infected easily. I think
Will water flow more easily through a wide pipe or a narrow pipe?
it would flow more easily through a narrow pipe
What is a blunt-tip dive knife?
Many dive knives have blunt (squared-off) tips. This makes them safer. You're not likely to need a sharp-tipped knife underwater. You're more likely to just need the cutting edge. Sharp tipped knives tent to snap off and break when prying at things. The blunted tip is more practical as you never need to stab anything but you often need to pry things underwater. A sharp knife is what you need for cutting line and old netting etc.
