An 8400-kg truck is traveling on a level horizontal curve, resulting in an effective lateral force H (applied at the center of gravity G of the truck).Treating the truck as a rigid system with the center of gravity shown, andknowing that the distance between the outer edges of the tires is 1.8 m,determine (a) the maximum force H before tipping of the truck occurs,(b) the minimum coefficient of static friction between the tires and roadwaysuch that slipping does not occur before tipping.
3. A vehicle, mass 1400 kg, passes a bend at a speed of 54 km/hr. The radius of curvature of the road is 60 m. Determine the minimum coefficient of static friction between the car tires and the road, so that the car can pass through corners safely.
A belt of negligible mass passes between cylinders A and B and is pulled to the right with a force P. Cylinders A and B weigh, respectively, 5 and 20 lb. The shaft of cylinder A is free to slide in a vertical slot and the coefficients of friction between the belt and each of the cylinders are µs = 0.50 and µk = 0.40. For P = 3.6 lb, determine (a) whether slipping occurs between the belt and either cylinder, (b) the angular acceleration of each cylinder.
