Enter your name and student number in the spaces below. Name: SONU VARGHESE GEORGE Student number: 17717 Each question has several answers, only one of which is correct. Select your answer by typing # in the box. When complete, save the file using the same name. Then use the upload facility to return it for marking. 1. In practice, to ensure the correct chemical composition of a new piece of steel we: Subject a sample to a Brinell test Subject a sample to macro examination # Obtain a mill certificate Obtain the mill delivery note 2. A destructive test which measures stress over strain in a steel sample is known as:  An impact test #  A tensile test  An Izod test  A pendulum test 3. We can determine the ductility and malleability of a material from:  An impact test #  A tensile test  An Izod test  A pendulum test 4. Typically, the tensile strength of mild steel is: 245MN/m² 340MN/m² # 460MN/m² 540MN/m² 5. Typically, the extension of higher tensile is: 25% # 22% 20% 10% 6. A Charpy test measures a materials: # Resistance to brittle fracture Hardness Young’s Modulus Resistance to bending 7. A test which measures the return swing of a pendulum is known as:  A Brinell test  A hammer test  A clock test #  An Izod test    2 © Lifting Equipment Engineers Association 2012 - training\1-6e6e0000  8. The effect of a notch in a piece of material under load is to: Increase the ductility Increase the elasticity # Concentrate the stress and so act as a failure point Concentrate the oxides and so act as a corrosion point 9. A simple test used to check the ductility of welds is known as:  A Brinell test  A macro examination  An Izod test #  A bend test 10. In conducting a macro examination to determine the grain size and flow of a forging: #  A prepared surface is visually examined The surface is coated in a dye and sprayed with a developer The surface is magnetised and viewed under a periscope  A prepared surface is viewed under ultra-violet light 11. A Brinell test is made by: Striking the test piece with a pendulum # Indenting the surface of the test piece Polishing and etching the surface of the test piece Magnetising the test piece 12. The Brinell test is used to measure: The ductility of a material The elasticity of a material The plasticity of a material # The hardness of a material 13. Higher tensile steel gear, hardened and tempered should have a Brinell number of: Between 120 and 143 Between 143 and 193 # Between 152 and 217 Between 248 and 302 14. A method commonly used in the work place to detect surface cracks in welds is: The Charpy test The Izod test The radiographic test # The dye penetrant test 15. Magnetic detection will locate cracks and fissures: # To within approximately 10mm depth of the surface Only at the surface On materials up to a maximum of 25mm thickness  Anywhere within the line of magnetic flow 16. A method of crack detection which utilises electromagnetic induction is known as: Magnetic crack detection # Eddy current crack detection Radiographic crack detection Ultrasonic crack detection    3 © Lifting Equipment Engineers Association 2012 - training\1-6e6e0000  17. Radiography is a method of non destructive testing using: # Photographic film High frequency sound waves Magnetic flux Liquid penetrant 18. Which of the following is a non-destructive test? Izod test Tensile test Bend test # Hardness test 19. A proof load (force) test should never exceed: # The SWL The yield stress #  The elastic limit Young’s modulus 20. LEEA Technical Requirements require test machines to have a minimum accuracy of: +0 - 1% +1% - 2% # ±1.5% #  ±2% Marking  Answers still shown in black were correct  Answers now shown in red were incorrect – the correct answers are shown in blue Result 90%
