The phrase "rack one's brains" is an idiomatic expression that refers to the act of putting a tremendous amount of effort or exertion into deep thinking, mental concentration, and intense problem-solving. The term is typically used when a person is struggling to find a solution, answer a difficult question, or come up with new ideas.
When someone racks their brains, they engage in active mental exploration, often pondering and exploring every possible option or idea, in an attempt to uncover the correct answer or solve a complex problem. This intense cognitive activity involves thoroughly examining all available information, considering various perspectives, and delving deeply into one's memory and knowledge.
The term "rack," in this context, can be understood as a metaphor for stretching or straining the brain, similar to how a medieval torture device, the "rack," was used to forcefully stretch a person's body.

The phrase is commonly used in situations that require creativity, analytical thinking, or meticulous attention to detail. People may say, "I've been racking my brains all day trying to solve this math problem" or "We need to rack our brains and come up with a brilliant marketing strategy."
