4. Linking in technical objects

5. Mechanical Engineering is… A branch of engineering that focuses on the design, production, analysis, working and improvement of technical objects with moving parts

6. A link allows… Two or more parts of a technical object to be held together

7. In mechanics, a component is… a part or fluid that performs a mechanical function

8. Linking is… The mechanical function performed by any component that connects different parts of a technical object

9. The degrees of freedom are… The set of independent movements that are possible for a given part in a technical object

25. Characteristics of links p. 218

26. 1 st Characteristic pair Direct Indirect

27. Direct A direct link exists when two parts can hold together without requiring a linking component

28. Cell Phone > Case

29. Indirect An indirect link exists when the parts require a linking component to hold them together

30. Arm > Frame ?

31. 2 nd Characteristic pair Rigid Flexible

32. Rigid A rigid link exists when the surfaces of the linked parts or the linking component are rigid

33. Base > monitor

34. Flexible A flexible link exists when the surface of the linked parts or the linking component can be deformed

35. Pages > spine

36. 3 rd Characteristic pair Removable Non-removable

37. Removable A removable link exists when linked parts can be separated without damaging them

38. Laces > eyelets

39. Non-removable A non-removable link exists when separating the linked parts damages them or the linking component

40. Sole > upper ?

41. 4 th Characteristic Pair Complete Partial

42. Complete link There is a complete link when there is no movement between linked parts

43. Top > bottom

44. Partial There is a partial link when at least one part is capable of motion with respect to the other

45. Cap > pen

46. Guiding Controls Work book p. 221 Text book p. 431

47. Guiding is… The mechanical function performed by any component that controls the motion of one or more moving parts

48. A Guiding Component or Control is.. A component whose mechanical function is to guide the motion of moving parts

49. Adhesion is… The phenomenon by which two surfaces tend to remain in contact with each other without slipping

50. In Mechanics, Friction is… A force that resists the slipping of one moving part over another

51. Lubrication is… The mechanical function performed by any component that reduces friction between two parts

52. Main Types of Guiding

53. Translational Guiding Ensures the straight translational motion of a moving part

54. Translational Guide

55. Rotational Guiding Ensures the rotational motion of a moving part

56. Rotational Guide

57. Helical Guiding… Ensures the translational motion of a moving part while it rotates about the same axis
