This example demonstrates a 3D four-bar free chain mechanism. Key mathematical concepts include geometric construction and solid geometry. Using GeoGebra commands such as points A, B, C, D, E and barras, a dynamic model of the four-bar free chain is constructed. Suitable for high school students and researchers.

AI Drawing Prompt Reference

Create a 3D geometric model of a four-bar free chain mechanism. Place five points A, B, C, D, and E in distinct 3D locations. Then connect them in order with straight segments AB, BC, CD, and DE, forming four consecutive connected bars. Display the entire set of segments in space so the linkage path from A through B, C, D to E is clearly visible. Build it by placing the points first, then drawing the segments.
