- 1Structure:Any object that provides support.
- 2Structural Strength:A structures capacity to hold itself up, as well as any weight added to it.
- 3Structural StabilityA structures ability to maintain its position even when being acted on by a force.
- 4Name 3 structures:1.Solid
2.Shell
3.Frame - 5Solid Structure:Formed of a solid piece (or solid combination of pieces) of some strong material.
- 6Frame Structure:Made up of a rigid arrangement of parts, or structural components, fastened together.
- 7Shell Structure:Has a solid outer surface, which may be rounded or flat in shape, and have a hollow inner area.
- 8Functions:The use or purpose of a an object.
- 9Force:A push or pull that tends to cause an object to cause an object to change its movement or shape.
- 10Functions of a structure:-Transporting
-Sheltering
-Protecting
-Lifting
-Containing - 11Aesthetics:The pleasing appearance of a structure.
- 12External Force:A force applied on a structure by something else.
- 13The effect a force has on a structure depends on 3 things:-The magnitude, or size, of the force.
-The location of the force
-The direction of the force - 14Mass:The amount of matter in an object.
- 15Newton (N):The amount of force to hold up mass of 100 g.
- 16Gravity:External Force.
- 17Center of Gravity:Imaginary point where the downward force of gravity acts.
- 18Increase a structures stability:Increase the width of its base relative to its height.
- 19Load:An external force on a structure.
- 20Static Load:A load that is not moving.
- 21Dynamic load:A load that is moving.
- 224 types of Bridges:-Beam bridge (common and support at its 2 ends)
-Truss bridge (lightweight, strong, made of trusses (triangles))
-Suspension bridge (Tall towers at both ends and cables)
-Arch bridge (Designed to withstand heavy loads) - 23Performance requirements:Conditions that a structure must meet after it is built.
- 24Internal forces:Forces acting within a structure.
- 25Internal forces include:-Compression (when parts of a body press or push against each other)
-Tension (when parts of a structure press or pull away from each other)
-Shear (when parts of structure move in opposite directions from each other) - 26Complementary forces:When different types of internal forces act within a structure at the same time.
- 27Deformation:The change of shape in a structure or any structural component because the material is unable to resist the load acting on it.
- 28Flexibility:The ability of a material to be bent without breaking .
- 29Friction:The force that results when the surface of one object moves against thee surface of another object.
