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

The left pedal is left hand thread so that if the bearings seize the pedal comes loose. This is safer than bearings seizing and jamming against riders foot and causing a crash. It also protects the crank arm from having it's threads ruined. The right side bottom bracket (on the crank axis) is LHT for the exact same reasons, if the bearings seize, the crankset comes loose instead of causing a crash, and this protects the more expensive frame from thread damage.
