Scene tag
Flexible strips used to construct pivots. In real life flexures have zero friction and very little wear. Red and yellow dots are so that Phun users can see accuracy by examining the centration of the red dot in the yellow one.

Thanks for asking. Flexure bearings have some advantages over conventional bearings and Algodoo does a fairly good job of modeling them. They are often used in precision instruments because of their predictable, repeatable, low friction behavior. With flexures the material is allowed to bend. I imitate flexible material by making it out of multiple segments that are connected by double hinges.

The scene is set up to show a comparison of 3 flexure hinges. The crank and connecting rods are to introduce the same amount of deflection to each flexure.
