Bow design and mechanics testing with PVC models

[PatM]

  The mechanics of a limb with a static tip seem like they have less disruption of their power stroke.
 You can find lots of discussion regarding the way a longer working limb has a "bulge" or ripple in the limb on the return.
 Sometimes the wording that people choose to try to describe these actions may not be wholly accurate though.

Pat- Could you explain better what "disruption of power stroke" is?

[PatM]

If you look at slow motion videos you can see some interesting stuff going on as the limbs return. These  movements of the limb have various types of impact on the energy delivery.
 I'm not going to speculate exactly how.
 It can all be explained mathematically though.

I have seen videos that show limbs flexing in mid- limb after the bow reaches brace height, but never one showing a limb with static tips, just before....

a link would be helpful

I don't have a link, that's just how people have tried to explain things on other threads. Less working limb, less distortion.

   With a straight bow you san even see the handle start moving towards the archer before the limbs return.
