Construction in general is a novel topic to me and I was wondering if I could get some information from someone more knowledgable than I am. I had a discussion with a friend about the pulling capacity of a bulldozer (A situation with a mutual friend of ours, long story). The overall question is whether or not a John Deere 550G would be capable of pulling a loaded dump truck (around 70,000 lbs max), that was stuck in sand, out of it? How would the ground level, sand, and friction affect the situation? Although this is random, it is kind of relevent to me because I'm actually a student at NCSU considering changing from my current major to civil engineering. I can't help but to be curious as all the googling I have done has only resulted in dead ends! Your responses will be greatly appreciated!
