A truck has been fitted with a tilt bed. It has a 500 kg crate on the bed, which has been elevated to 30°. Determine the smallest acceleration of the truck necessary to slide the crate off the bed. The static coefficient of friction between the crate and the bed is 0.6. Draw clear and complete FBD and kinetic diagrams. Assume there is no tipping of the crate.
