How can one determine the value of static friction in a given scenario?
To determine the value of static friction in a given scenario, you can use the equation: static friction coefficient of static friction x normal force. The coefficient of static friction is a constant that depends on the materials in contact, and the normal force is the force exerted perpendicular to the surface. By calculating these values, you can find the static friction force acting in the scenario.
If a curve with a radius of 60 m is properly banked for a car traveling 60 kmh what must be the coefficient of static friction for a car not to skid when travelling at 90 kmh?
To prevent skidding at 90 km/h, the car would need a coefficient of static friction of at least 0.25. This value can be calculated using the formula: coefficient of friction = tan(theta), where theta is the angle of banking. Given the curve radius, speed, and the formula, we can determine the necessary value for the coefficient of friction.
Coefficient of friction for glass on wood?
The coefficient of friction between glass and wood can vary depending on factors such as surface finish and moisture content. However, on average, the coefficient of friction for glass on wood is around 0.4 to 0.6. This value indicates moderate to high friction between the two surfaces.
The lower the value of the coefficient of friction. the blank the resistance to sliding?
The lower the value of the coefficient of friction, the lower the resistance to sliding.
What can you say about the value of the coefficient of static friction and its significance in determining the resistance to motion between two surfaces in contact?
The coefficient of static friction is a measure of how difficult it is for two surfaces to start sliding against each other. A higher coefficient means more resistance to motion. It is important in determining how much force is needed to overcome this resistance and make the surfaces move.

Is coefficient of friction or coefficient of limiting friction are same?
Limiting friction is just the maximum static friction force (if you go over that point static friction becomes kinetic friction).Let f = frictional force,c = coefficient of frictionN = Normal forcefmax = cN = limiting frictionAlthough the term coefficient of limiting friction is not really used, I'd assume it would just be "c" (it's a coefficient after all). So they would be the same.If you meant is coefficient of friction the same as limiting friction, than the answer is no. Coefficient of friction is just the "c" in the equation. Limiting friction however is the product of the coefficient and the normal force.

How can an adjustable inclined plane be used to measure the coefficient of static friction and coefficient of kinetic friction?
Place the object on the plane. Slowly increase the angle of the plane until the object begins to move at angle Θ. The µs = tan Θ. For µk, same process, but give the object a little push at each increasing value of Θ.
What pattern do you notice about the values for the coefficients of friction?
The coefficient of friction typically ranges from 0 to 1, with 0 indicating no friction and 1 indicating high friction. The coefficient of friction depends on various factors such as the surfaces in contact, surface roughness, and whether the surfaces are in motion or at rest. In general, smoother surfaces have lower coefficients of friction compared to rougher surfaces.
Which has a maximum value kinetic friction or static friction?
The maximum value of static friction is typically greater than the maximum value of kinetic friction. Static friction is the force required to overcome the initial resistance of an object at rest, while kinetic friction is the force required to keep an object in motion.
What is the expression for the maximum value of friction for which the block will not slide down the incline?
The expression for the maximum value of friction for which the block will not slide down the incline is given by the equation: ( ftextmax mus cdot N ), where ( ftextmax ) is the maximum friction force, ( mus ) is the coefficient of static friction, and ( N ) is the normal force acting on the block.
Is it true that kinetic friction is always greater than the maximum value of static friction?
Yes, it is generally true that kinetic friction is always greater than the maximum value of static friction.
The lower the value of the coefficient of friction the what resistance to sliding?
The lower the value of the coefficient of friction, the lower the resistance to sliding. A lower coefficient of friction means less force is needed to overcome the resistance between two surfaces, making sliding easier.
