CXC/CSEC School Based Assessment (SBA)

Mechanical Engineering Technology

Due Date: March 30, 2020                                                               Date Given:     _March 13, 2020

Do a PowerPoint presentation on Machine Devices. The presentation should use up most of the features of PowerPoint. This should include:

• The first slide as a cover page
• Interesting animations and transitions with sounds,
• creative slides with pictures and interesting background,
• slides with large font size writing
• easily understood slides with description beside pictures.
• The last slide giving references

It should be presented:

1. on letter-size paper, printed as handout with 6 or 9 slides per page.
2. on a storage device, such as cd, sd card, or flash drive; (preferably the CD)
3. As an emailed to your teacher (mrfrancis1best@gmail.com)

Machine Devices

With the aid of pictures, briefly (one or two sentences) describe and show uses of each type of the following machine devices:

1. Mechanical Keys for shafts:
   • square key,
   •  gib-headed key,
   • tapered key,
   •  woodruff key
2. Shafts,
3. Pulleys
4. Couplings:
   • Rigid couplings (sleeve coupling, compression coupling, flange coupling)
   • Flexible couplings (universal coupling, Oldham coupling, Bush pin type coupling)
5. Gears
   • Spur gear
   • Rack and pinion
   • Internal ring gear
   • Helical gear
   • Face gear
   • Worm gear
   • Hypoid gear
   • Bevel gear
6. Bearings –
   • Friction bearings or plain bearings
     • Bushing
     • Flanged bushing
     • Fluid bearing
   •  Anti-friction bearings
     • Ball bearings
     • Roller bearings
     • Ball thrust bearings
     • Roller thrust bearings
     • Tapered roller bearings
     • Magnetic bearings
7. Belts –
   • Flat belt
   • Round belt
   • V-belt
   • Cogged belt
8.  Mechanical Chains
9. Seals (Single spring seal, multiple spring seal, O-ring seal, V-ring seal, Wedge ring seal, Metal seal, elastomeric seal, TFE seal)
10. Gaskets (Non-metallic gasket, semi-metallic gasket, metallic gasket)

For this Machine Devices presentation, approximately 50 slides are the norm and are expected.
