Match the statements in Column B to the tems in Column A. Write down the answers only, for example 1. (a). Column A Column B 1. Test place (a) defined as the increase in strain per 100 000 hours of continuous static loading and expressed as a smal percentage per hour 2. Stress (b) uses reflection between two parallet imiting faces of the test specimen (c) refers to the mechanical testing of grey 3. Young's modulus of elasticity cast iron (d) value of the increment in stress divided by the coresponding increment in strain, for the straight portion of the stress-strain (or load-extension) diagram (e) the ratio between the sound pressure of the reflected wave Pr and the pressure of the incoming wave Pe Grey iron castings 5. Load at yield point 6. Structure examination n carried out after test piece examination to remove the residual magnetism, which is undesirable and dangerous 7. Reflection factor R (9) the load at which the extension of the test piece first increases without increase of load or with decrease of load (h) load divided by original cross-sectional area of the parallel portion of the test 8. Echo method piece an important application of ultrasonic measuring techniques - especially with castings, concrete, or ceramics and where sound velocity and sound attenuation are measures 9. Demagnetisation 10. Creep rate O the portion of the test sample on which the tensile test is caried out [10]
