Yes and no .. This is what I mean with the is it better or worse - would it cause a different failure ?It's effectively the same setup, with a solid mount at the bottom that, therefore, makes the whole yoke effectively a solid part of the shock and, in turn, gives the rest of the rear end more leverage to "bend" the shock. Using your bike pump analogy, imagine welding on a 4-6" bar on the end of the pump and grasping that. It would snap even faster, no?
If you welded you bar onto my pump (my poor pump ) ... Yes, you'd have more leverage and could boomerang it far easier. So yes, definitely by making it longer, you're applying a higher leverage force which if the "pump" wasn't designed for that, it would fail sooner.
If we attached your bar onto my pump with a hinge instead (like the levo clevis) It would be harder for you to snap the pump because you'd just be bending at the hinge as you tried to boomerang it . BUT !!!!
If we first used your welded bar, with the bar on the floor, standing vertically, and hit it with a sledge hammer downwards - it would most likely just compress the pump. The further off vertical it is, the more effect your bar will have on causing a fail rather than compress.
If we used the hinged one, for starters it would want to flop over on the hinge - so we can't even try to hit it to make it fail - because it can move .. But if we supported it temporarily them hit it, the pump/shock/clevis would flex at the hinge, the bottom of the pump would hit the floor off to the side - the same distance as the length of your hinged bar extension and the pump would probably snap as it wouldn't have the forces controlled vertically through it. The welded bar I see as the Kenevo linkage, the hinge as the Levo.
There is an advantage to welding the bar in one situation, which also works as a disadvantage in the other situation.
There is an advantage in hinging it in the first situation, but that works as a disadvantage in the second situation.
