Question

What is the reason of excessive friction between parts?​

Answer 1

Answer:

Answer:What is the reason of excessive friction between parts?

ans..Increasing the area of surfaces that are touching also increases the friction between them. That's why you can't slide as far across ice with shoes as you can on the thin blades of skates. The greater surface area of the soles of the shoes cause more friction and slow you down. Heavier objects also have more friction.

hope you got it....

Answer 2

Answer:

Excessive friction between parts can occur for several reasons, like surface roughness, temperature, lubrication, wear and tear, etc.

Explanation:

1) Surface roughness: If the surfaces of the parts are rough, they will experience more friction than if they were smooth.

3) Lubrication: A lack of lubrication can cause excessive friction, as the parts will rub against each other without any protection.

4) Temperature: Friction increases as temperature increases, as the parts will expand and become more prone to sticking together.

5) Wear and tear: Worn or damaged parts can experience more friction, as their surfaces are no longer smooth.

Friction

• Friction is a force that opposes motion between two surfaces that are in contact. It is the result of the roughness of the surfaces, their material properties, and the load applied to the surfaces.
• Friction generates heat and can cause wear and tear on the surfaces in contact.

The formula for frictional force (F) is given by:

F = μ × N

where:

• μ (mu) is the coefficient of friction, which is a dimensionless constant that depends on the materials in contact and their roughness.
• N is the normal force, which is the force perpendicular to the surface and acts to keep the objects in contact.
