I had to look it up:
Rack vs. wrack
Wrack is roughly synonymous with
wreck. As a noun, it refers to destruction or wreckage. As a verb, it means to wreck. It is now mostly an archaic word, preserved mainly in a few common phrases.
Rack has many definitions, but the one that makes it easily confused with
wrack is
to torture. This sense comes from the use of medieval torture devicescalled rackson which victims bodies were painfully stretched. So, figuratively speaking, to rack something is to torture it, especially in manner that resembles stretching.
Common rack/wrack phrases
Rack {ones} brain
Rack {ones} brain is one common phrase in which rack in the torture-related sense is figuratively extended. To rack ones brain is to torture it or to stretch it by thinking very hard.
To wrack ones brain would be to wreck it. This might sort of make sense in some figurative uses, but
rack is the standard spelling where the phrase means
to think very hard. Wrack {ones} brain is so common, though, that we have no choice but to consider it an accepted variant (some dictionaries agree with this).
