The figure below shows a crate with a mass of m= 2.75 kg on a surface inclined at an angle of 35.0°. The coefficient of static friction between the crate and the surface is 0.285. Find the minimum magnitude of the force F (in N), applied to the crate in a direction perpendicular to the surface, that will prevent the crate from sliding down the surface. m 35.0⁰ 21.717 X Draw a free-body diagram. Let your axes be parallel (x) and perpendicular (y) to the incline. What i the direction of the normal force? The applied force, F? Applying Newton's second law in the perpendicular direction, what is the normal force? How is the maximum static friction force related to the normal force? Applying Newton's second law in the parallel direction, can you find F?

Transcribed Image Text:The figure below shows a crate with a mass of m= 2.75 kg on a surface inclined at an angle of 35.0°. The coefficient of static
friction between the crate and the surface is 0.285. Find the minimum magnitude of the force F (in N), applied to the crate in a
direction perpendicular to the surface, that will prevent the crate from sliding down the surface.
