Structures: Form and Function

3. basic shape of a structure
6. science of designing equipment that people can use more efficiently and safely
7. ability of an object to withstand forces, such as compression, tension, shear, and torsion
8. any small or large object that provides support and has at least one function
9. force that one part of a structure exerts on other parts within the same structure (e.g., shear, tension, compression, torsion forces)
10. force applied to a structure from the outside (e.g., wind, gravity)
11. breakdown of a structure due to the internal and external forces acting on it
13. type of internal force that pushes a structure in opposite directions
14. structure that is solid all the way through
15. ability of a structure to maintain or resume its position when an external force has been applied to it
17. part of a structure that can add strength to it (e.g., arches, beams, columns)
19. force that moves or changes while acting on a structure
20. structure that is made of parts fastened together
21. exact location where a force meets a structure
23. external force acting on a structure
24. type of internal force that stretches a structure apart to expand or lengthen it
25. person who buys and uses anything grown or made by producers

1. type of internal force that squeezes or presses a structure together
2. company or person who produces and sells products that consumers buy
4. model used to test and evaluate a design
5. structure containing a combination of shell, frame, and solid structures
11. effect of gravity on a structure
12. any push or pull acting on a structure that can change the structure’s shape, speed, or direction
13. structure that is strong, hollow, and light for its size
15. effect of all the internal and external forces acting on a structure over a long period of time
16. side of a structure affected by a force
18. type of internal force that twists a structure
22. purpose of an object or structure
