When using the composite, we are led to evaluate in what sense the forces of extension and compression will be exercised. Indeed, unlike metals, composites have a strength "anisotropic", that is to say, it depends on the direction of fibers embedded in resin.

Although qu'isotropes, that is to say equally strong in all directions, les métaux […]

The goal is to go take pictures in the desert, obvious is that I have little chance of finding a spare parts in the corner. Une par­ti­cu­la­rité de mon pro­jet est qu’il intègre d’emblée la casse comme devant arriver.

On a theoretical, the famous Murphy's laws (dont cha­cun  a sa propre […]

That said, it is quite nice, manufacturing quality seems better than previous models, but a number of things vex me.

La pre­mière, c’est le côté […]
