Structures

1. Properties

   • Strength
     • Is its ability to withstand external forces without breaking
   • Forces
     • Is an influence that can deforme a body or change its movent,or produce motion in a body at rest
   • stresses
     • are the phisical ndemands that a body or object
   • Rigid
     • Does not deform
   • Elastic
     • Deforms but thenreturnsto its origunal shape
   • Plastic
     • Deforms and stays deformed

2. A structure is a colection of elements arranged in an optimum way to supporta body or an object

3. TYPES OF STRESS

   • Compression
   • Tension
   • Bending
   • Torsion
   • Shear

4. ELEMENTS THAT INCREASE STABILITY

   • By widening the base of the structure
   • By locatind the centre of gravity of the structure at a low point
   • By making a good foundation for the structure
   • By supporting the structure with stay cables
