Can you solve these physics riddles? ft Simone Giertz - Part 1/3

There are two lefty screws. One is on the right side of the bottom bracket (drive side), and the other is on the left side pedal. Both way, the reason is so the screw can't jam itself into the thread. Turns out it is not as big a deal to have a pedal/bottom bracket which has yeeted from the bike, as having one, which you have essentially welded to the bike, while pushing it down with your entire weight.
