Compute all parts of given question:
Question: An 80 N crate of apples sits at rest on a ramp that runs from the ground to the bed of a truck. The ramp is inclined at 30° to the ground.
Part A: What is the normal force exerted on the crate by the ramp?
Part B: What is the static frictional force exerted on the crate by the ramp?
Part C: What is the minimum possible value of the coefficient of static friction that will prevent the crate from sliding?
