3. Provides a structure for thinking and doing

4. The scientific formula for work is

5. Involves the effort you put in and the distance over which you maintain the effort

6. A fixed wheel with a rope or chain that is attached to a load - used to change the direction of a force or to lift heavy objects - is a

12. Seeks to meer our needs and wants and to extend our capabilities

13. The English unit of measuring work

14. If you generate alternative solutions and begin to build your best solution - but you have problems building your design - what should you do?

15. A wheel fixed to a support with a rope that is run over the wheel to change the direction of a force applied to the rope

16. A wheel that meshes with a sliding toothed bar - converting rotary motion to reciprocating (to- and- fro)

17. A bar or rod that tilts on a pivot - or fulcrum

23. A lever in which the fulcrum is at one end - and the effort is at the other end

24. Models that function and look like the finished product but are usually hand- built

25. A system of pulleys that consists of one rope wound around two separate sets of pulley - each of which is free to rotate independently on the same axle
