Im having a bit of trouble with this problem: A crane of mass 5288.51 kg supports a load of 789.67 kg. The crane are is 7m long and the angle it makes wiht the horizontal is 47.627 degrees. The distance between the front and rear wheels is 4 m. Assume that the center of mass of the crane, is at the center of the crane and that the crane arm is of negligible mass. The reaction force at the rear wheels is Nr and at the front is Nf. The sum of these is Nt (total reaction force at the ground). Find Nt and Nr. ------------------- There is a drawing to go along with this.... it makes it easier to visualize... the crane is basically a rectangle sitting on the ground. The rear wheel is just represented by the back of the rectangle and the front wheel by the front. The cranes arm is sticking out of the front at the bottom. If anybody could point me in the right direction i would greatly appreciate it!
