This reduces strain on the spine, arms, and knees while improving speed and control on uneven surfaces. This modification is done to prevent long-term injuries, increase daily productivity, and allow one worker to move heavy materials safely without exhaustion. #const

While gravity's natural role is to pull objects toward the Earth, these clever LEGO-like mechanisms use a transfer of energy to overcome the "one-way" nature of dominos. Each domino is mounted on a pivot. When one falls, it hits a lever or a gear system that uses the force of the fall to "reset" a domino further down the line. By arranging these pivots in a circle and adding a small motorized element (or a pr
