  1. Year 8 Technology Resistant Materials Name Form Group

  2. levers What is a lever? Why are levers useful? There are three types of lever. Draw a diagram to show the effort (input) pivot (fulcrum) and load (output) for each one: First Class Effort L P Second Class L Effort P Third Class L P Effort Give some examples of levers around the home: http://www.technologystudent.com/forcmom/lever1.htm

  3. Existing levers

  4. List some ideas for your lever project

  5. Get some pictures from the internet from the list

  6. http://www.technologystudent.com/cams/link1.htm Linkages • Why are linkages important? • What does a linkage do? • Name two linkages: • 1)… • 2)… • What is a Toggle Clamp? • Where on the body would you find a Toggle Clamp?

  7. Pulleys What is a pulley? Where would you find a pulley? www.lego.com/education/school/default.asp?l2i... What sections can you get belts in? What are the advantages of stepped belts or chains? Where would you find stepped bets and chains?

  8. There are FOUR basic types of motion: Motion Something which travels in a perfectly straight line has linear motion List some things that have linear motion: • Repeating backwards and forwards motion in a straight line is known as reciprocating motion List some things that have reciprocating motion: Circular movement is known as rotary motion List some things that have rotary motion: Fixed point • Repeating backwards and forwards circular movement is called oscillating motion List some things that have oscillating motion:

  9. Gears http://www.technologystudent.com/gears1/geardex1.htm If gear A has 60 teeth and gear B has 30 teeth, what is the ratio? What does the Idler gear do? Where would you find a Rack and Pinion? Where would you find a Bevel Gear? Where would you find a Worm Gear?

  10. Lever Project My Final Design Insert picture from the M or Z Drive- Year 8 resistant- Finished projects Mr Westcott’s group Write about your project.

  11. Evaluation – levers project • Describe your finished project: • Does it look like your original design? • Do your levers work? • Explain what happens • Would you like to change anything? • Did you enjoy making it? • Did you have time to finish it? DESIGN YOUR FINISHED PROJECT MATERIALS WHAT IT DOES PRODUCED THE PLAN YOU MADE FIRST FUNCTION WHAT YOU USED TO MAKE IT PRODUCT HOW IT WAS MADE Match these words to their meanings:

  12. Box joints - partitions • Why are partitions used? • 2. Describe these three joints: • Butt joint • b) Housing joint • Stopped housing joint 2. Label these three joints used to partition boxes: b. c. a.

  13. Chisels Name the two types of chisel shown a. b. 1. What are Chisels used for? 2. What other tool can be used with a chisel? 3. How can you stop the wood from splitting? 4. Give two safety rules to follow when chiselling:

  14. Paste into Paint Go to View/Zoom/Large size check for any gaps Colour in surfaces Light/medium/dark Use colours edit colours to get correct shades Load 2D Design Right click on the dots Click on isometric Click on Grid lock Use the line tool to draw your shape Draw a box around the shape Edit select all Edit Copy Draw a box around the finished shape and copy onto the next slide

  15. Copy and paste your picture from 2D Design here

  16. My DVD Rack Design Insert picture from the M or Z Drive- Year 8 resistant- Finished projects Mr Westcott’s group Write about your project.

  17. Collect pictures for your picture frame/mirror project

  18. Insert picture of mirror from the M Drive- Year 8 resistant- Finished projects Mr Westcott’s group Describe how you made your final project

  19. Give a score for the following 1=Excellent 2=Good 3= Satisfactory 4=Poor How much have you enjoyed the projects? 1-4 1= I enjoyed it a lot 4= I didn’t enjoy it at all Explain your answers: Two targets for next year:
