(Macro View) Foil Profiling Machine — Technic Experiments Shaping a profile… mechanically. Seen up close. This LEGO Technic experiment showcases a foil profiling machine, filmed with macro close-ups to reveal how every linkage, pivot, and contact point works together. The mechanism converts rotation into smooth, repeatable curves — no CNC, no software, just precise mechanical guidance. Macro view exposes what’s usually hidden: micro-movements, tolerances, and real contact between parts. Pure mec

In-Situ SEM Material Testing: Micro-Tensile Testing The macro tensile test (macrotraction), while providing valuable information about the general properties of the material, determines the average of the effects of each constituent present in the matrix, such as the different phases or interfaces. To quantify the properties of a single phase or interface, microtraction tests are required, as shown in the video. In addition, by further reducing the dimensions of the specimens, unique mechanisms
