Across
- 2. A 2D perspective showing just the top of an object.
- 3. A curved shape in a vertical plane that spans an opening and supports a weight.
- 4. A test of the sturdiness of a structure, where the structure is dropped from the teacher’s shoulder height.
- 8. A body is not elastic if it either does not bend or if, when it does bend, it does not return to its original shape.
- 9. A weight imposed on an object.
- 13. A simple machine where a bar is free to pivot about a fixed point when a force is applied.
- 16. To make alterations to an original design in order to improve upon it.
- 17. The weight supported by a structure or part.
- 18. Any source of wealth that occurs naturally, especially minerals, fossil fuels, timber, etc.
- 21. A standard sheet formatted for a particular kind of drawing.
- 22. A situation that involves losing one quality of something in return for gaining another
- 24. A material’s ability to resist an applied force (i.e. doesn’t break).
- 26. The tendency of a body to return to its original shape after it has been stretched or
- 27. An iterative 8-step process used by engineers to develop a product. It emphasizes testing prototypes and redesigning.
- 29. A force related to the stretching of an object.
- 30. A two-dimensional perspective showing just the face of an object.
- 31. A 2D representation of a 3D object. It shows the front, side, and top (“plan”) views with parallel lines as if it is being looked at straight on.
- 32. The force applied to a machine.
- 33. A force related to adding a load on two sides of an object.
Down
- 1. A natural resource that cannot be produced, re-grown, regenerated, or reused on a scale which can sustain its consumption rate. This includes coal, petroleum, oil, and natural gas.
- 5. Firmly built or constructed. Elements that make a structure sturdy include a solid base and the use of triangles. Resistant to some loading and other external forces.
- 6. The fixed point about which a lever turns.
- 7. The weight or object being acted on by the lever; the result of the effort.
- 10. A lever where the effort is applied between the fulcrum and the load.
- 11. A natural resource that is replaced by natural processes at a rate comparable or faster than its rate of consumption by humans. This includes fresh water, plants, and wood if managed sustainably.
- 12. The resistance encountered when one body is moved in contact with another.
- 14. A part of engineering design that allows the engineer to test a product or part of a product on a smaller scale or using cheaper materials before the final product is manufactured.
- 15. The careful utilization of a natural resource in order to prevent depletion.
- 19. A three-sided polygon. A triangle is the strongest shape because it cannot be deformed without changing the length of one of its sides or breaking one of its joints.
- 20. A lifelike representation of an object that uses length, width, and height to create the illusion of depth. Here is a 3D image of the object represented by the above multiview drawing.
- 23. Remaining diverse and productive over time.
- 24. A 2D perspective showing just the side of an object.
- 25. A cooperative or coordinated effort put forth by a group of people in the interest of a common goal.
- 28. A non-handheld mechanical devices used to throw a projectile a great distance without the aid of an explosive substance.
