Chapter 3, Problem 3/199 The hydraulic braking system for the truck and trailer is set to produce equal braking forces for the two units. If the brakes are applied uniformly for 9 seconds to bring the rig to a stop from a speed of 35 mi/hr down the 10-percent grade, determine the magnitude of the force P in the coupling between the trailer and the truck. The truck weighs 16,000 lb and the trailer weighs 12,000 lb. 35 mi/hr 10 100 Answer: P = the tolerance is +/-2% lb

The hydraulic braking system for the truck and trailer is set to produce equal braking forces for the two units. If the brakes are applied uniformly for 8 seconds to bring the rig (truck and trailer) to a stop from a speed of 32 mi/hr down the 5-percent grade, determine the force P in the coupling between the trailer and the truck. The truck weighs 19,000 lbs and the trailer weighs 15,000 lbs. State whether the coupling is in tension or compression.
6.11 A wheel tractor-scraper is operating on a level grade. Assume no power derating isrequired for equipment condition, altitude, and temperature. Use equipment data fromFigure 6.10. a. Disregarding traction limitations, what is the maximum value of rolling resistance (inlb/ton) over which the fully loaded unit can maintain a speed of 15 mph?b. What minimum value of coefficient of traction between the tractor wheels and thetraveling surface is needed to satisfy the requirements of part a? For the fully loadedcondition, 52% of the weight is distributed to the drive axle. Operating weight of theempty scraper is 74,946 lb.
A wheel tractor-scraper is operating on a 3% adverse grade. Assume no power derating is required for equipment condition, altitude, and temperature. Use equipment data from Fig. 6.7.

A 2500-lb passenger vehicle originally traveling on a straight and level road gets onto a section of the road with a horizontal curve of radius = 850 ft. If the vehicle was originally traveling at 55 mi/h, determine (a) the additional horsepower on the curve the vehicle must produce to maintain the original speed, (b) the total resistance force on the vehicle as it traverses the horizontal curve, and (c) the total horsepower. Assume that the vehicle is traveling at sea level and has a front cross-sectional area of 30 ft2.?

Problem 9.4 The 2975-lb car is parked on a sloped street. The brakes are applied to both its front and rear wheels. (Figure 1) Figure 1 of 1
A wheel tractor-scraper is operating on a level grade. Assume no power derating is required for equipment condition, altitude, and temperature. Use equipment data from Fig. 6.7. Disregarding traction limitations, what is the maximum value of rolling resistance (in lb/ton) over which the fully loaded unit can maintain a speed of 10 mph? What minimum value of coefficient of traction between the tractor wheels and the traveling surface is needed to satisfy the requirements of part a? For the fully loaded condition, 50% of the weight is distributed to the drive axle. Operating weight of the empty scraper is 89,973.0 lb.

The driver of a 1000kg car traveling on the interstate at 35.0 m/s slams on his brakes to avoid hitting a second vehicle in front of him, which had come to rest because of congestion ahead. After the brakes are applied, a constant friction force of 8000 N acts on the car. Ignore air resistance. (a) At what minimum distance should the brakes be applied to avoid a collision with the other vehicle? (b) (b) If the distance between the vehicles is initially only 30.0 m, at what speed would the collision occur? AX
