Question:
The tractor and scraper units shown are connected by a vertical pin located 1.8 ft behind the tractor wheels. The distance from C to D is 2.25 ft. The center of gravity of the 20-kip tractor unit is located at Gt, while the centers of gravity of the 16-kip scraper unit and the 90- kip load are located at Gs and G1, respectively. Knowing that the tractor is at rest with its brakes released, determine
(a) The reactions at each of the four wheels,
(b) The forces exerted on the tractor unit at C and D.

Take 2 forks and place them on one another in such a way that we can place the coin in between the prongs. Now try to place the coin with forks on the edge of the glass. It will take you some time to adjust the coin on the edge. This requires a little practice to adjust the coin on the edge of the glass. With a little effort, we will see the coin sitting on the edge calmly. If you look closely you will see it wobbling a little bit. The mass is in the handles of the forks so as a low center of mass it stables as it looks.
