Objects with a low center of gravity and a wide suport base tend to be more stable than objects with a higher center of gravity.
FUN FACT: A long pole helps lower an acrobats center of gravity.
These are beams. They are designed to help support a load. I-beams are a stronger beam shape. They are lighter than steel beams but can support a very heavy load. Corrugation is a folded beam. Corrugation is used to add additional strengths to many roofs, boxes and even metal.
Another example of a beam is rebar. Rebar is steel reinforcement bars. They are placed in concrete to help it resist the force of tension and compression. Last but not least is he cantilever. It is a beam that is only supported on one end. They are very common, mostly used as canopies.
FUN FACT: The Observation Tower in Niagara Falls has a cantilever a little over the falls.
Ties, Struts and gussets are supports for the beams. A tie is built to resist tension forces and it is placed above the beam. Struts are built to resist compression and it is placed under the beam. A gusset is often triangular and is reinforcing the connection between the beam and its support base.
There is such thing as structural failure. It is a part of the structure of the whole structure itself that is weak to support a load. By that, the structure would collapse or break. It can be caused by either bad design of the structure, faulty construction, extraordinary loads (too much force), or foundation failure.
FUN FACT: The leaning tower of Pisa has been built slanted. Now, the tower is a tourist attraction as it is still standing.
I hope you both enjoyed your tour but I have to go do another with 3 people this time. Bye! TOODOOLOO!
Thank you very much for that tour. She really did want to know all that. Good Luck on the next tour!
I wish we could of had him to take us home as well!
