10. Tungsten is the correct material for a light bulb filament, Titanium as the correct material for spectacle frames

11. Question 6

12. Provides a uniform weld bead, Produces a slag-free weld bead, Allows welding in all positions, Requires less operator skill than TIG welding, Allows long welds to be made without starts or stops, Needs little cleanup

13. Question 7

15. Question 8

16. Cubic boron nitride (CBN) is the second hardest material after synthetic diamond. The desirable characteristics of an abrasive include high hardness, strength, abrasion resistance, and thermal and chemical resistance, and an ability to maintain sharp cutting edges during use.

29. Question 15

30. piezoelectric transducers produce charge when squeezed; heat is applied in order for shape memory polymers to return to their original shape.

31. Question 16

33. Question 17

35. Question 18

36. Better fuel efficiency than a conventional aircraft (1) because the blended wing is designed to have less drag (1) Lower noise than conventional aircraft (1) because of its aerodynamic design that allows use of smaller engines (1) Increased load carrying capacity for the relative size of the aircraft (1) because their innovative design utilises space more efficiently (1) Can fly at lower speeds/altitudes/easier lift off than conventional jet aircraft (1) because of the greater surface area providing lift (1) Improved handling or flying characteristics/lower stall characteristics than conventional jet aircraft (1) because of a more stable design with improved gliding characteristics (1)

37. Question 19

38. Using Kaizen gives Electrobox assembly workers responsibility for suggesting improvements to quality processes and assembly techniques in the production of electrical switch panels. However, Kaizen techniques may not be effective if the assembly workers are resistant to change and managers are not fully commited to its introduction. If Kaizen is adopted by all assembly workers and managers at Electrobox, it can be a highly effective way to reduce waste through empowering all Electrobox employees to engage in continuous improvement.
