Yes but in practice that means using glue, at which point you might as well glue everything together into a single piece.
- IAmBroom 1y agoNot glue, necessarily. The coefficient of friction is not about surface adhesion. It is kinetic; glue is an additional static component.
- amelius 1y agoAre you talking about changing the geometry of the blocks?
- Liftyee 1y agoThe difference is that glue can withstand tension which changes a lot. Even infinite friction still requires a non-negative contact force (i.e. the surfaces are not being pulled apart).
