The tractor has a weight of
4500 lb with center of gravity at G. The driving traction is
developed at the rear wheels B, while the front wheels at A are
free to roll. If the coefficient of static friction between the
wheels at B and the ground is s = 0.5 possible to pull at P = 1200
lb without wheels at B to slip or the front wheels the ground.

17-87. The tractor has a mass of 900 kg, excluding the rear wheels. The mass center is located at G. Each of the rear wheels has a mass of 50 kg and a radius of gyration A-0.7 m. If the tractor coasts freely down the 10° slope, determine its velocity when -5s starting from rest. For the calculation, neglect the mass of the front wheels B and the effects of friction at these wheels. The rear wheels roll without slipping...
