I assume they mean that once tensioned, it will not "give" and lose it's tension. > [although it was VERY > little, there is no way of knowing how much it will stretch w/ 2700lbs > pulling and 240" of belt]. Knowing the belt modulus or stiffness it is a very simple calculation. Unfortunately I haven't been able to find that critical number for that belt type. Not wanting to re-open a can of worms, but there were some calculations done a few months ago on this very subject. (is there an archive?)
