697: Tensile vs. Shear Strength
|Tensile vs. Shear Strength|
Title text: Although really, the damage was done when the party planners took the hole punch to the elevator ribbon to hang up the sign.

Tensile strength represents how hard you can pull on something without it breaking. Shear strength represents how hard you can try to cut it without it breaking. Many materials have great tensile strength but low shear strength (such as dental floss — try to break it by just pulling on two ends), including whatever this space elevator is made of. The material clearly has extremely high tensile strength because it can hold the elevator in place, with one end on the ground and one in space, but it can be cut with a simple pair of pruning shears. This also highlights the fact that "shear strength" and "shears" are etymologically related.
The title text makes the point that even before Black Hat cut the space elevator's cable in two, it was ruined by the holes in it for the banner. The holes would reduce the surface area of the cross section of the pole, dwarfing its ability to keep the elevator attached to the ground. The flag and holes would also potentially make it impossible for the elevator to travel up the pole, making the entire elevator useless.
- [A space elevator occupies the height of the frame, consisting of a base, a cable extending out into space, and an elevator unit with standard elevator features such as sliding doors and up/down buttons. A banner flutters in the breeze attached to the cable going up above the elevator there is text on the banner. Text appear in four lines split across the elevator cable itself, the rhyming portions of the text is on the right side of the cable. Five individuals stand at the base of the elevator. To the left are Megan, a Cueball-like guy, with his arms up, and Ponytail who has recently opened a bottle of champagne holding it up while spilling some of the liquid out the top of the bottle because she holds it and her other arm up. To the right is Black Hat, who cuts the cable with a pruning shear like it was part of the ceremony as a ribbon cutting. Finally further right is Cueball who sees what Black Hat is doing. He is very alarmed holding a hand to his mouth while holding the other out towards Black Hat.]

After countless engineers spend trillions over fifty years, a modern babel disappears because some fuck brought pruning shears
- Pruning shears: Snip
- Cueball: !!
