## What is the minimum coefficient of friction?

Friction coefficient as low as 0.05 between dry sliding surfaces has been achieved when the mechanical interactions are eliminated.

## What is the minimum value of static frictional force and under what conditions?

As you keep adding more force, you will reach a peak where friction is equal to the maximum static friction. If you overcome that, the object starts moving and you get kinetic friction. The minimum value of friction is equal to 0, which happens when the object is on a perfectly smooth surface like ice.

**How do you find the maximum static friction coefficient?**

The maximum or limiting value of friction between two surfaces is FMAX=μR F MAX = μ R where μ is the coefficient of friction and R is the normal reaction between the two surfaces. The coefficient of friction is a measure of the roughness of the surface – the rougher the surfaces the larger the value.

**What minimum value must the coefficient of static friction have if the pipe is not to slip?**

For no slipping to occur, the coefficient of static friction must be greater than or equal to (1/3)tanθ ( 1 / 3 ) tan θ . Thus, the greater the angle of incline, the greater the coefficient of static friction must be to prevent the cylinder from slipping.

### Which of the following is minimum static friction?

The coefficient of rolling friction is minimum because the rolling friction requires a particular amount of friction so that the point of contact between the wheel and the surface be sufficient to stop the sliding of the wheel.

### What is the minimum coefficient of static friction needed to prevent the wheels from slipping on the corner?

1 Answer. David G. Centripetal acceleration is given by a=v2r . The minimum friction coefficient required is 0.4 .

**How do you find the minimum force?**

(F= μ N), where μ is the coefficient of friction between the two surfaces. Afterwards, while the object is in motion, SLIDING FRICTION is the resisting frictional force.

**How do you calculate the maximum static frictional force between the object and the surface?**

How to find force of friction

- Choose the normal force acting between the object and the ground. Let’s assume a normal force of 250 N .
- Determine the friction coefficient.
- Multiply these values by each other: (250 N) * 0.13 = 32.5 N .
- You just found the force of friction!

## What is the static friction coefficient?

It is a ratio of the force of friction between two bodies and the force pressing them together. The coefficient of static friction is the ratio of the maximum static friction force (F) between the surfaces in contact before movement commences to the normal (N) force.

## Which friction is minimum static or kinetic?

The static friction between two surfaces is always higher than the kinetic friction (at least, in practical, real-world applications).

**Which friction is minimum static limiting or kinetic?**

The kinetic friction is less than the limiting friction.
