Linkages
This example demonstrates a 3D four-bar linkage. It involves core geometric construction concepts such as circles, lines, and points. Using GeoGebra commands like Circle, objects O, c, U, E, F, l1, l2, e, f, C, l3, a dynamic model of the four-bar linkage is constructed. Suitable for high school or university mechanical engineering and geometry courses.
GeoGebra Commands & Parameters
Circle(O, 1, zAxis) → c
AI Drawing Prompt Reference
Construct in 3D a circle with the point O as its center and radius equal to 1. Place the circle on a plane whose orientation is determined by the z-axis direction (zAxis), so the circle’s alignment relative to the coordinate axes is clear. First specify the center O and the radius 1, then use the zAxis direction to define the circle’s plane, and draw the circle.
