I designed this umbrella and then got to put it in a wind tunnel. Think you guys might like to see it. Not often you get to see your design pushed to failure. This was an initial prototype with 3D printed plastic so we ramped the speed up right away. The umbrella has to be tied down so it doesn’t become a spear. The failure happened after the base started bending. The umbrella lifted up and the force between the patio table and the tie down caused the plastic part in the center to break. When I tested the umbrella with actual molded parts the umbrella only broke when it flew up into the air and then slammed down into the ground. I’ll post that footage soon
