Why is it difficult to hammer a blunt nail

A blunt nail has more surface area than a sharp nail, so the pressure applied is less.

Why is it difficult to hammer a blunt nail in wood?

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 it difficult to insert a blunt nail in wooden block?

Yes, it is difficult to insert s blunt nail in a wood block because there is a law which states that if there is more area then less will be the pressure and if there is less area then more will be the pressure.

Why is it easier to hammer a sharp nail than a blunt one?

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.

Is it easier to hammer a blunt nail into a piece of wood than a sharply pointed nail?

False. It is not easier to hammer a blunt nail into a piece of wood than a sharply pointed nail.

Why it is difficult to cut vegetables with a blunt knife?

ANSWER: It is difficult to cut vegetables with a blunt knife because it has more area compared to a sharp knife, which means that the pressure exerted by the blunt knife is less than that of the sharp knife.

Why do we always strike the board end of the nail with a hammer and keep the other end in contact with the wall?

So, that is why if we keep the end side of the nail which has very small area ,in contact with the wood then get to apply less pressure on the broader side of the nail which make it easier for us to fix it into the wood.

How does the pressure exerted on the object change when the force applied on an object is doubled?

Answer: When the force applied on an object is doubled the pressure exerted on object is also doubled as it is directly proportional to the force.

How does the medicine enter a dropper?

When you squeeze the rubber top of a dropper, you squeeze out the air out. This causes the pressure inside the dropper to be lower than the pressure outside. Due to this, the air pressure outside pushes the liquid and this allows it to enter the dropper.

Why is it difficult to push a nail into a wooden plank by its head?

Pressure is inversely proportional to area. The area in more in the head of the nail ,therefore it requires much pressure. Hence it is hard to push a nail into wooden plank by its head.

Why is it easy to push a nail?

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 will be the pressure more on the pointed end rather than the blunt end support your answer with an example?

Explanation: because sharp nail has smaller area than the area of blunt nail . So sharp nail gets more pressure fix easily into the wall than the blunt nail .

What is atmospheric pressure Why do we not feel its effect?

The reason we can’t feel it is that the air within our bodies (in our lungs and stomachs, for example) is exerting the same pressure outwards, so there’s no pressure difference and no need for us to exert any effort.

How would pressure change if force is doubled keeping area constant?

If area is doubled keeping the force constant, then pressure becomes half. If force is doubled keeping area constant, then pressure becomes double.

Why is it difficult to hammer the head of a nail into a wall?

The Head of the Nail has Higher area , which makes the way for distribution of pressure onto the wall (i.e Pressure at an single point decreases) .

Why do my nails keep bending when hammering?

If you’re bending the nail each time, it usually means the hammer is hitting the nail at a slight angle (or too big a hammer!) The head must hit the nail head perfectly flat to drive it in straight. … If you’re nailing close to the end of a piece of wood, try tapping the point on a nail to flatten it.

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.

Why is it difficult to cut fruits with a blunt knife?

It is because the surface of the fruit is large and a blunt knife occurs more surface than a sharp knife so it doesn’t cut easily while when we use a sharp knife it cuts easily because it occurs a small surface of fruit then that of blunt knife.

Why is it easier to cut vegetables with a sharp knife *?

Pressure is inversely proportional to the area of the surface. A sharp knife has a smaller area that comes in contact with the object and hence more pressure can be applied on the object. … Therefore it is easier to cut with a sharp knife.

Why is it difficult to cut vegetables with a butter knife?

If surface area increases (for a blunt knife it becomes more than the area for a sharp knife), then pressure decreases. … If pressure decreases then less force is applied on the vegetables resulting in difficulty in cutting them.

How do you feel the air around you?

Air is constantly pushing against us, but it feels more like pressure than weight since it pushes from all sides. This all-around push is called air pressure.

What is meant by atmospheric pressure Name two devices that work on atmospheric pressure?

1)Syringe : When piston of a syringe is pulled up, it is atmospheric pressure outside that forces up the liquid into the syringe. 2)Straw : When a person sucks up the liquid from straw the pressure inside is relatively low and thus atmospheric pressure outside forces up the liquid into straw.

How pressure changes as the force exerted changes?

The pressure exerted on a surface by an object increases as the weight of the object increases or the surface area of contact decreases. Alternatively the pressure exerted decreases as the weight of the object decreases or the surface area of contact increases.

What are the factors affecting pressure exerted by a solid?

A solid resting on a horizontal surface exerts a normal contact force equals to its weight. The pressure of the solid on the surface depends on the area of contact. (b) the area of contact between the two surfaces. The greater the force or the smaller the area the greater the pressure.

Does the pressure exerted on the object change?

As pressure is force on a unit area, it depends on what grounds do you double the force.. For example if you double the force and let the area remain constant, then the pressure is doubled. But if you double force as well as area, then it doesn’t change at all it remains the same.

Why do we fix a nail in a wooden plank at pointed end and not on flat end Class 8?

it is to fix through pointed end because it has less surface area and force exerted by us will produce more pressure.

Why is it easy to pull downward?

When we pull an object on the horizontal plane, then the vertical component of the force will act vertically downward and will increase the weight of the object leading to an increase in friction. … So, when there will be less force of friction, it is easier in that case to move the body.

How do fluids exert pressure?

Why Fluids Exert Pressure The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions.

Why is it easy to push sharp end of nail into the wall than pushing its head?

It is easy to push a nail by the pointed end because pointed end has got less area due to which it experiences a greater force. So it is pushed in the wall.

What are the four main effects of force?

• A force can move a stationary object.
• A force can stop a moving object.
• A force can change the speed of a moving object.
• A force can change the direction of a moving object.
• A force can change the shape and size of an object.

What do you understand by state of motion?

But what is meant by the phrase state of motion? The state of motion of an object is defined by its velocity – the speed with a direction. Thus, inertia could be redefined as follows: Inertia: tendency of an object to resist changes in its velocity. … Objects resist changes in their velocity.
