Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. The condition of a string - wire - or rod that is stretched between two points.
Tension
Composite
Fatigue
Stiffness
2. The ratio of the increment of some specified form of stress to the increment of some specified form of strain - such as Young's modulus - the bulk modulus - or the shear modulus. Also known as coefficient of elasticity - elasticity modulus - elastic

Cross -Sectional Area
Modulus of Elasticity
3. When a material is reduced in volume by the application of pressure; the reciprocal of the bulk modulus.
Compression
