WebNormal forces are normal — that is, perpendicular to a tangent drawn to a curve or surface. This crate isn't currently going anywhere, so all the forces perpendicular to the incline must cancel. For a static crate on an incline, the force normal to the incline equals the perpendicular component of its weight. N = W⊥. N = 965 N. WebProblem 3: The coefficient of static friction between the 3.00-kg crate and the 35.0° incline of the figure below is 0.300. What mini-mum force F must be applied to the crate perpendicular to the incline to prevent the crate from sliding down the incline?
