crucifixion
磔 centers on the act of crucifixion: a form of execution where a person is bound or nailed to a cross. The meaning is specific and does not extend to general punishment or religious symbolism beyond the given gloss.
磔 combines 石 (stone) with 桀, which likely contributes the sound and is associated with dismemberment or exposure. The character originally referred to a form of execution involving tearing apart or exposing the body, later associated with crucifixion.
The left side 石 suggests a heavy stone, and the right side 桀 looks like a person spread out. Imagine a person being tied to a stone cross for crucifixion.
For タク, picture a tack being driven into the stone cross during crucifixion: tack -> タク, and the sharp sound echoes the act.
