Sense: adjective/1
All four describe a shape that is not straight, but they differ in cause and feel. 'Curved' is the most neutral and often suggests a smooth, designed shape, like a curved roof or curved coastline. 'Bent' usually implies that something straight has been forced out of its original shape, often by accident or pressure — a bent nail, a bent spoon, a bent knee. 'Crooked' adds a sense of unevenness or untidiness; a crooked picture frame is annoying to look at, and a crooked smile is charmingly uneven. 'Warped' is reserved for flat surfaces like wood or metal that have twisted because of heat, water, or age, as in a warped door that no longer closes properly. So you might say: 'The curved bridge looked beautiful, but the bent guardrail and the warped wooden planks made it dangerous to cross.'

Etymology
'Bent' began life as the past form of the Old English verb 'bendan', meaning to fasten or pull a bow into a curve. Over time, anything pulled out of a straight line could be described as 'bent', and the word became an adjective in its own right. The figurative uses grew naturally from this picture: a person 'bent on' something is mentally pulled toward it like a drawn bow, and a 'bent' for an activity is the inner pull that draws someone to it. The British informal sense 'corrupt' is a more recent slang extension, treating a dishonest official as a person who has been twisted from the straight path.
