8–39. The car has a weight of 4000 lb and a center of gravity at G. If it pulls off the side of the road, determine the greatest angle of tilt θ it can have without slipping or tripping over. The coefficient of static friction between its wheels and the ground is μs=0.4. Problem from Engineering Mechanics Statics, Fifteenth Edition.
