3 What are the 3 parts that make up a mechanical system?
A Human mechanism Reaction B Input Process Output C Pulley gear Lever D Force Reaction Outcome

4 What are the 3 parts that make up a mechanical system?
Can you give an example when using a product? A Human mechanism Reaction B Input Process Output C Pulley gear Lever D. Force Reaction Outcome

5 A lever is the simplest kind of mechanism, it consists of…..
A A flexible bar that rotates at a fixed point. B A rod that will only move horizontal C Two bars that change the direction of motion. D A ridged bar that pivots at a fixed point.

6 A lever is the simplest kind of mechanism, it consists of…..
Name a product or action that uses a lever mechanism. A A flexible bar that rotates at a fixed point. B A rod that will only move horizontal C Two bars that change the direction of motion. D A ridged bar that pivots at a fixed point.

7 £2,000

8 A lever has 3 named parts, they are…….
A Load, fulcrum and effort. B Weight, pivot and energy. C Input, process and output. D Load, pivot and energy.

9 A lever has 3 named parts, they are…….
Can you remember the rhyme we have learnt to help you remember? A Load, fulcrum and effort B Weight, pivot and energy. C Input, process and output. D Load, pivot and energy.

10 £4,000

11 A The weight that is put onto something.
The load is …. A The weight that is put onto something. B The load is the object you are trying to move or effect. C What is added to the lever. D The weight that effects the lever.

12 Give me an example of a load for any lever mechanism.
The load is….. Give me an example of a load for any lever mechanism. A The weight that is put onto something. B The load is the object you are trying to move or effect C What is added to the lever. D The weight that effects the lever.

13 £8,000

14 A The point where the lever pivots.
The fulcrum is…. A The point where the lever pivots. B The area of the lever that is full. C The point that doesn't move from it's spot. D The area that is effected by the load.

15 A The point where the lever pivots
The fulcrum is…. Give me an example of the fulcrum in any product or action that uses a lever A The point where the lever pivots B The area of the lever that is full C The point that doesn't move from its spot. D The area that is effected by the load.

16 £16,000

17 The effort is…………. A What you need to do to make it work. B The measurement of input C Trying very hard to make it work. D Where the force is added.

18 A What you need to do to make it work B The measurement of input
The effort is ………. Give me an example of the effort in any product or action that uses a lever A What you need to do to make it work B The measurement of input C Trying very hard to make it work. D Where the force is added.

19 £32,000

20 A Has the effort in the middle B Has the load in the middle
A class one lever……. A Has the effort in the middle B Has the load in the middle C Has the fulcrum in the middle. D Can have either the fulcrum or load in middle.

21 Give me an example of a class 1, 2 and 3 lever.
A class one lever… Give me an example of a class 1, 2 and 3 lever. A Has the effort in the middle. B Has the load in the middle. C Has the fulcrum in the middle. D Can either have the fulcrum or load in middle.

22 £64,000

23 A An “idler” gear. B The connective gear. C The rotational gear.
What is the gear called in the middle? A An “idler” gear. B The connective gear. C The rotational gear. D The reverse gear.

24 What does the idler gear do? (what is its function)
What is the gear called in the middle? What does the idler gear do? (what is its function) A An “idler” gear B The connective gear C The rotational gear. D The reverse gear.

25 If A gear turns close wise, what direction will gear G turn?

26 £125,000

27 A bevel gear…. A Reduces the speed of a machine or tool.
B Changes the axis of rotation through 90 degrees. C ,Changes the direction of the output by 360 degrees. D Changes the axis of rotation by 360 degrees.

28 A bevel gear…. A Reduces the speed of a machine or tool.
B Changes the axis of rotation through 90 degrees. C Changes the direction of the output by 360 degrees. D Changes the axis of rotation by 360 degrees.

29 Explain how this bevel gear works on the hand whisk.
Why does the smaller gear turn faster than the large gear it is attached to?

30 £250,000

31 This mechanism is a ……….. A pulley B Lever C Gear D cam

32 What are pulley’s used for?

33 £500,000

34 If you increase the amount of pulleys in a system………
A It increases the mechanical advantage. B It makes it easier to lift a heavy load. C It decreases the effort needed to lift a load. D It increases the amount of belt/rope needed.

35 If you increase the amount of pulleys in a system………
A It increases the mechanical advantage. B It makes it easier to lift a heavy load. C It decrease the effort needed to lift a load. D It increases the length of belt/rope needed.

36 £1,000,000
