STRUCTURES

STRUCTURES

1. FORCES:Is anything that can defrom a body or changeits state of rest or movement.

2. STRUCTURES: A structure is a set of elements in a body that are intended to resist the effects of the forces that act on it.

3. TYPES OF STRUCTURES:A structure prevents a body form breaking or becoming too deformed

4. LOADS:A load is the force that acts on a structure

5. STRESSES:Stresses are the effects that loads cause in a structure

6. TYPES OF STRESSES: - Traction - Compression - Bending -Torsion - Shear

7. STRUCTURAL CONDITIONS:The conditions for a structure to work well are:-Stability -Resistance - Rigidity

8. STRUCTURAL CONDITIONS:The stability depends on -The centre of gravity of the object

9. STRUCTURAL CONDITIONS:We can give a structure stability by: -Adding mass ti its base - Bracing it - Burying its bottom sectio underground

10. STRUCTURAL CONDITIONS: Resistance depends on: -The material used to build the structure.

11. STRUCTURAL CONDITIONS: Rigidity comes from:-Making rigid joints -Using triangular structures
