WebSep 12, 2024 · Thus, (a) f s = 20.0 N, (b) f s = 30.0 N, and (c) f s = 120.0 N. (d) If P → = 180.0 N, the applied force is greater than the maximum force of static friction (137 N), so the crate can no longer remain at rest. Once the crate is in motion, kinetic friction acts. Then (6.4.12) f k = μ k N = ( 0.600) ( 196 N) = 118 N, and the acceleration is

Coefficient of Static Friction Formula - GeeksforGeeks

WebStatic friction is the force holding an object in place on an incline, such as the cheese in Figure 1. The friction force points against the direction that the object would slide without friction. Static friction keeps gravity from pulling the cheese down the incline. WebThe formula for the Coefficient of static friction is, μs = F/N (now, putting value from the problem into the given equation) = 90/80 = 1.125 So, the Coefficient of static friction is 1.125.

"WebJun 17, 2024 · If the crate is to move with the truck when it accelerates at 5.0 m/s 2, the force of static friction must be (6.5.17) f s = m a x = ( 50.0 k g) ( 5.00 m / s 2) = 250 N. Since this exceeds the maximum of 196 N, the crate must slip. The frictional force is therefore kinetic and is (6.5.18) f k = μ k N = ( 0.300) ( 4.90 × 10 2 N) = 147 N.
