- 1dynamic loadsany outside force that acts on an object
- 2static loadsare caused by the force of gravity
- 3dead loadDo not change. The structure always supports them and it is caused by the force of gravity acting on it
- 4Live loadlive loads are the things the structure supports. They are caused by the force of gravity acting on all the parts that are not apart of the structure.
- 5shell structuresolid outside hollow or fragile inside, curved outside
- 6solid structurehard throughout very heavy, carry lots of dead weight
- 7tensionwhen something is being stretched out
- 8torsioninternal, created when an object is twisted
- 9compressionwhen something is pushed together to compress it
- 10shearinternal, object is pushed or pulled in opposite directions and the objects bends, rips, tears, or snaps.
- 11center of gravitya point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the center of mass.
- 12designing stable structuresWide base, narrow top, lowering centre of gravity,
- 13stable shapespyramids are the most stable shapes because they have a narrow top and a very wide base.
