Introduction to Materials
Points of consideration: * Strength * Stiffness Ching (2.08-2.11) * Shape * Behaviours Static Loads - applied slowly until peak load * Economy is reached, then remains relatively stable. * Sustainability * Ground pressure Types of Materials: * Water pressure * Timber * Thermal stresses
[e-Learning]:
* Dead loads - from structure itself
* Steel -------->
* Glass
* Concrete -->
* Brick
Compression - loads that push down on a structural member, causing particles to compress
Tension - loads that pull on a structural member, causing the particles to stretch and elongate

[Key Terms]: Reaction Force a force that is diagram that illustrates equal and opposite to the applied force the flow of a load through a structure. Direction and magnitude is identified Load Path
[e-Learning]: Loads Paths: -
Beam a structural element, an illustration that shows the disnamely steel or timber, that acts as a support persion of the force from the load through a and is arranged horizontally in the structure. structure and to the ground. Load Paths show both magnitude and direction due to forces being vector in nature. A reaction force a load that is local- Flange that is equal and opposite is also presented Point Load to illustrate the structure is in balance. ised to a specific area of a strucutre Web

a type of force whereby the force is down the structure, causing compression of particles

[Tower building exercise]: Rough idea of how the structure would be assembled: Circular in shape in order to ensure the load is dispersed evenly, due to the absence of corners where excessive loads occur.
Drawing upon the masonry of brick work, and how the forces of loads are dispersed through a certain arrangement of each component, we based our structure off this method.
Working off these two concepts, we contrsucted a strong base by laying down two rings of wooden blocks. This was to ensure the structure would remain stable even when getting higher and higher. A difficulty we came across when building our structure was building our doorway from either side to join in the middle. This posed as a concern as the load from the two distinct sides cased the blocks to gradually slope downward, leading to the inability to successfully join either sides of the doorway on a common level.
