You use both everyday, Just don’t know it. Common sense all it is.
I use it. Will this load shift on truck placed on X spot. can my 60,000 pound winch drag up a dumpster weighing 30,000 pounds at a certain degree of angle ? seems like a yes answer, but have to figure in terrain, truck angle, truck length, dumpster height hitting overhead power lines. etc. common sense. have it or you don’t. sure 60,000 pound winch sounds great pulling a 30,000 pound dumpster. Everything has to add up to make it work. If on a incline, will i run out of fuel from the truck being shifted to one side and cant pump/suck enough fuel. 1/2 tank of fuel will be empty on gauge.
Will be a ass calling your boss, " hey i ran out of fuel " can’t get this load on. take an hour to get it restarted. ( no never happened to me ) but a co-worker yes.
meanwhile have 40 gallons of fuel on level ground that just shifted to 1 tank on the incline angle …
You use algebra / geometry everyday.
Yes sir
