Video insights

@engineezy's TikTok video "How does a piece of fishing line make this car roll? ••• One crank runs the whole stunt through a 9:1 gear train. Two cam grooves in the back plate control the car. One tilts it to match the ramp, and the other is a timer that swings a small rocker right after the car leaves the ramp. ••• That swing becomes the roll through a capstan. A loop of braided fishing line runs from a drum on the rocker, up the tube, and around the car’s axle. The drum is 2.4 times bigger, so 75° of swing turns into exactly 180° of roll. ••• The full breakdown, with a 3D model you can crank yourself, is at https://engineezy.com/blogs/project-details/how-the-roadster-ramp-flip-works ••• #engineering #mechanicalengineering #mechanisms #automata #3dprinting" has 73,697 views, 3,496 likes, 47 comments, 22 shares in the public metrics captured by this index.
