Origin

Mid 17th century (originally describing a gas in the sense 'expanding spontaneously to fill the available space'): from modern Latin elasticus, from Greek elastikos 'propulsive', from elaunein 'to drive'.

First recorded in the 1650s, elastic was originally used to describe the way that gas is able to expand to fill whatever space is available. In those days some people thought that gas particles acted like a coiled spring, an idea that led elastic to take on its modern sense. The word comes from Greek elastikos, from elaunein ‘to drive’.

The concept of Newtonian elastic collisions among molecules of a gas suffices to bind together in one theory the empirical laws of Boyle, Charles, and Graham. As the temperature decreases the elastic energy increases and eventually causes a shear in a part of the matrix, which stabilises the rest. The theory attributed the behaviour of gases to the motions and elastic collisions of a large number of molecules. nounəˈlastikəˈlæstɪk Cord, tape, or fabric, woven with strips of rubber, which returns to its original length or shape after being stretched. （尤指织入了橡皮筋的）弹性绳；松紧带；弹性织物 Example sentencesExamples The dress was a knee length halter, with no sleeves, but just enough elastic to hold it onto Amanda's pre-teen chest. After doing some research, I discovered the answer: The dryer was destroying the rubber elastic in the socks and underwear.

Strings or elastic might be attached inside the skirt to keep the back fullness and the bustle in place. The leg elastic didn't pinch and kept the shorts in place. She fastens it there with a strong hair elastic, and uses a hatpin to attach the cloth flower. Use a large needle to thread thin elastic through the mask, knotting elastic at each end to create a band. White rubber elastic is strong and stable and is commonly used in competitive swim-suits. Modern day carp poles are ideal for Irish fishing but remember to change the internal elastic for strong powergum as this will enable you to lift decent size fish without needing a landing net. I know too, that nylon and stretch elastic, cast aside by fishermen, catches around seabirds' legs and either slowly kills or maims them. It stretched across them like endless elastic. Stabilize seams as you sew with clear elastic or sheer tricot tape. New ribbons add extra flexibility and support for lacing up the leg, and mesh elastic blends seamlessly with tights while helping the shoe to fit more snugly. Pin strap elastic at center back, curving up to top of bra band. Take the fabric for the top and starting at the back end of the board, use your largest zigzag stitch to sew corded elastic to the edge, all the way around the board. Stretch the elastics quickly and touch them to your lips. In a drawer in the nightstand there was a brush and many hair elastics. Stretch the clear elastic several times to remove any future give. The same leg gripper elastic is also around the ankle area. Origin Mid 17th century (originally describing a gas in the sense ‘expanding spontaneously to fill the available space’): from modern Latin elasticus, from Greek elastikos ‘propulsive’, from elaunein ‘to drive’.
