A 142Kg create is placed on an inclined ramp. when the angle the ramp makes the horizontal is increased to (alfa), the crate beging to slide downward.

A) Draw a free-body diagram showing the forces acting on the crate.
B) Calculate equations representing the components the forces actiong on the crate.
C) if the coefficient of static friction between the crate and the ramp is 0.65, what is the angle (alfa) when the crate just begings to slide downward?
