"The marine diesel crankshaft was so thiccc the dock crane refused it on the first lift, citing a personal limit."
Etymology,
From crank (Middle English cranke, 'a bend or turn') + shaft (Old English sceaft, 'pole or rod'), with the maritime diesel sub-genre dating to Rudolf Diesel's 1893 patent. The ocean asked for power. The crankshaft replied with mass.
