### Simple machines

1. 1. SIMPLEMACHINESBy: Clarisse Mallari Chermaine de los Reyes Next
2. 2. At the end of the lesson, the classwill be able to identify the different simple machines. Back Next
3. 3. Simple MachinesConsidered to be building blocks of machinesIt helps the people make their work easierThe 1st machines are often called “the 6 simplemachines” LETS FIND OUT WHAT THESE MACHINES ARE! :-) Back Next
4. 4. The 6 SIMPLE MACHINES:click the machine you want to know :-)Lever Wheel & Axle ScrewInclined Plane Pulley Wedge Back Next
5. 5. Lever Resistance force / load Effort forceconstructed from a beam attached to ground by a hinge, or fulcrumThe fulcrum balances 2 forces: an effort force and a resistance force, or load Hinge/ Back Next Fulcrum
6. 6. These are some other examples of Lever machines :-) Back HOME Next
7. 7. Wheel And AxleA wheel with a rod, called an axle, through its center lifts or moves loads.Theyre everywhere! A large circle (wheel) connected to a smaller circle (axle) links distance traveled and power needed in an incredibly useful way Back Next
8. 8. These are some other examples of Wheel and Axle machines :-) Back HOME Next
9. 9. Inclined PlaneA slanting surface connecting a lower level to a higher level. Back Next
10. 10. These are some other examples of Inclined Plane :-) Back HOME Next
11. 11. PulleyA simple machine that uses grooved wheels and a rope to raise, lower or move a load.Each section of string supporting the movable pulley system decreases the force needed to move the load Back Next
12. 12. These are some other examples of Pulley machines :-) Back HOME Next
13. 13. WedgeAn object with at least one slanting side ending in a sharp edge, which cuts material apart. Back Next
14. 14. These are some other examples of Wedge:-) Back HOME Next
15. 15. ScrewAn inclined plane wrapped around a pole which holds things together or lifts materials. Back Next
16. 16. These are some other examples of Screw :-) Back HOME EXERCISE! :)
17. 17. Now, are you familiar with the simple machines youve seen?Lets test how you remember them. We will have some few exercises! Click the “Start” button if you are ready. Lets go! :-) Start Back
18. 18. What am I?You can usually find me during flag ceremonies, I help the flag reach the top of the pole. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
19. 19. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
20. 20. CORRECT! :)I am a pulley and you can usually find me ontop of the flag pole. It is easier for me to pull down and push up because of the movable rope that supports me :-) Back Next question
21. 21. What am I? I help Mr. Porter put the box to the truck.Lever Wheel and Axle WedgePulley Inclined Plane Screw Back Next question
22. 22. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
23. 23. CORRECT! :)I am a inclined plane and you can always useme as a guide to transfer heavy things inside a truck Back Next question
24. 24. What am I?Hey-o-hey-o, said the dwarf as he lift me to whack that rock into two. Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
25. 25. CORRECT! :)I am a wedge and you can always use me to cut materials apart because I usually have slanting side ending in a sharp edge :-) Back Next question
26. 26. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
27. 27. What am I? I am Mr. See-saw.Lever Wheel and Axle WedgePulley Inclined Plane Screw Back Next question
28. 28. CORRECT! :)I am a lever and I can be a seesaw for you and your playmate :-) Back Next question
29. 29. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
30. 30. What am I?“I need you,” said Mr. Hinge, “the Door and I cant connect.” Lever Wheel and Axle Wedge Pulley Inclined Plane Screw Back Next question
31. 31. CORRECT! :) I am a hinge. A hinge is a kind of screw thatyou can see between the side of the door and the wall attaching it. It is the one that makes the door open properly :-) Like this: Back Next question
32. 32. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
33. 33. What am I?The cyclist is looking for me, his bike wont move without me.Lever Wheel and Axle WedgePulley Inclined Plane Screw Back Next question
34. 34. CORRECT! :) I am a wheel and an axle. A bike is anexcellent example of it, because of the wheelthat makes it to move and a screw to secure it :-) Back Next question
35. 35. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
36. 36. What am I?“Cut-cut-cut” said the scissors. I will cut your paper into halfLever Wheel and Axle WedgePulley Inclined Plane Screw Back Next question
37. 37. CORRECT! :)I am a wedge and you can always use me to cut materials apart because I usually have slanting side ending in a sharp edge :-) Back Next question
38. 38. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
39. 39. What am I? “Wiii”, said the child as she slide on me.Lever Wheel and Axle WedgePulley Inclined Plane Screw Back
40. 40. WELL DONE! :)I am an inclined plane and sometimes I can also be a slide in playgrounds and fun parks :-) Next Back
41. 41. OOPS! THATS NOT ME. YOU CAN TRY AGAIN Try Again
42. 42. CONGRATULATIONS! You have successfully identified the different kinds of simple machines. You might think of it as “simple” yet it has many uses, and those are the special meanings in physics. When a force moves an object, that is what we now call “work” :-) Next
43. 43. I hope you have learned enough information about our topic today. Always remember, examples of these things are not simple machines: Next
44. 44. This is not a simple machine. This isWALL-E. A complex robot machine. Next
45. 45. Neither is Bumblebee fromtransformers. This is really a complex- transforming robot. Next
46. 46. Well yes. Washing machine makes your life easier, BUT this is notidentified as simple machine! It has complex functions in it Next
47. 47. Especially this! This is a machine. But this is machine gun, not for simple purposes. You know what I mean. Next
