A 142 kg crate is placed on an inclined ramp when the angle, Ask an Expert

Academics

a 142 kg crate is placed on an inclined ramp. When the angle the ramp makes with the horizantal is increased to ALPHA, the crate begins to slide downward.

a) draw a free body diagram showing the forces acting on the crate.

b) calculate equations representing the compontents of foces acting on the crate.

c. If the coefficient of static friction between the crate and the ramp is 0.65, what is the angle alpha when the crate just begins to slide downward.
