*15-8 The automobile has a weight of 2700 lb and is traveling forward at 4 ft/s when it crashes into the wall. If the impact occurs in 0.06s, determine the average impulsive force acting on the car. Assume the brakes are not applied. If the coefficient of kinetic friction between the wheels and the pavement is He 0.3, calculate the impulsive force on the wall if the brakes were applied during the crash. The brakes are applied to all four...

The crane truck has a weight of 11750 lb and a center of gravity at point CG. The parking brake only locks the rear wheels of the truck, so the front wheels are free to rotate. Determine the maximum force F applied at the angle = 32.5° that can be exerted on the crane without it slipping or tipping for each of the following cases: Case 1: The static friction coefficient between the rear tires and the ground is pe...

9:381 LTE Problem 1 A crest vertical curve is to be designed to join a +2% grade with a-2% at a section of a two-lane highway. Determine the minimum length of the curve if the design speed of the highway is 60 mph and SL. Assume that a-9.34 ftsec' and that the perception-reaction time is 2.5 sec. Problem2 A crest vertical curve is to be designed to join a +3% grade with a-2% grade at a section of a two-lane...
