We have a truck that weighs 20,000 lbs, 8,100 on the front and 11,900 on the rear. The wheel base from the front axle to the rear axle is 272". The center of gravity is 161.84" which we found by taking 272" * 11,900 / 20,000 = 161.84". What would the load be on each axle if we add a third axle that weighs nothing (for the sake of keeping it simple) at 220" that is an 'independent non-load sharing axle'? Meaning its just like the original rear axle and not like a normal tandem setup that shares (splits) a load evenly between the two. Any insight into this is much appreciated, Thanks. p.s. To get more into it what would the loads be on each axle when we add a payload of 26,000 lbs at 200"?
