SpletStatic and Kinetic Friction A 20.0-kg crate is at rest on a floor as shown in (Figure). The coefficient of static friction between the crate and floor is 0.700 and the coefficient of kinetic friction is 0.600. Splet18. jun. 2024 · 0.21. The minimum coefficient of static friction can be obtained from this equation: If the velocity of the car is 72 km/hr (20 m/s) and the radius of curvature R = 190 m, the minimum value of the coefficient of static friction is 0.21.
Splet02. sep. 2024 · At this point, the force on the object is just equal to the maximum value of static friction, i.e. μ m g cos θ where θ is the angle of incline. And what is the force on the object? Well, it's the other component of weight i.e. m g sin θ . For equilibrium condition, you equate these two- μ m g cos θ = m g sin θ from which you simply get- μ = tan θ SpletMechanical Engineering questions and answers. The coefficient of kinetic friction is calculated as the ratio of the: Normal force to the maximum value of the static friction force. Maximum value of the static friction force to the normal force. Normal force to the value of the force required to produce motion at constant velocity.
