On November 7th, 1940, the Tacoma Bridge collapsed into the Tacoma Narrows straight in Washington State. The bridge connected the town of Tacoma and the Kitsap Peninsula, and was one of the first major suspension bridges in the western United States. Unlike other suspension bridges constructed around this time, the Tacoma Bridge failed to withstand wind speeds over 40 miles per hour, due to unequal stress on parts of the bridge. The construction of a suspension bridge must include geometric…

one side to the other. (CambridgeDictionaryOnline.com) Bridges come in many different shapes sizes and designs. However there multiple different categories of bridges ranging from Arch bridge, Truss bridge, Cantilever bridge, Cable-Stayed bridge, Beam bridge and Suspension bridge, All ranging with different designs. All of the different bridge designs are made to withstand a specific amount of weight. A bridge supports weight when the base of the bridge is made out of strong and good material…

Failure occurs when a member reaches its limit, and cannot support any more load, therefore breaking (Sansano, 2013). The structural elements of the Waddell a-truss bridge include two trusses, which each have compressive and tensile components. The beams in the middle did not carry any immediate load, other than the one attached to the actual bucket. The way the load is placed meant that bars were in tension,…

When Steiner Studios built their first movie production building at the Brooklyn Navy Yard, David Steiner, CEO of Steiner Equities Group, knew that precast concrete construction was the perfect fit for the studio complex. Adding a third studio building at the city’s largest movie production complex, to increase the number of sound stages, Dattner Architects and general contractor the Steiner Group once more partnered with Oldcastle Precast Building Systems, specifing precast concrete components…

Part A: Here in Tennessee we are in a valley with lots of lakes and water falls between the mountains. The water falls have swinging bridges going across them and not everyone will walk across because of the fear of it breaking or swinging too much. So my idea is to have the children build a regular bridge with a roof that does not swing and sheds shade to those in wheel chairs can enjoy the water falls and bridge as well. In this activity we will use Lincoln logs to build a two layer bridge…

Fred Beam was born in Covington (near Atlanta), Georgia. His family moved to Tampa, which is near Florida, when he was a little boy. Fred’s parents were teachers, who were very devoted to their work. Fred was raised in a very mature and hard-working family. He was very persistent, patient, and very devoted to his work. It happened so that he was the only deaf member in the family. He got a good oral education in his childhood and early teens. After graduating, Fred entered Tampa Technical…

By Brigid Garrett , Wyatt Mullings, Jesus Sanchez, and Lydia Blaisdell Cable Sensation Russky Bridge, Vladivostok, Russia. What are Cable/Stayed Bridges? A cable/stayed bridge is a bridge that has two towers with cables supporting the bridge itself, as shown above. The towers are called pylon, the crossing area itself is called the roadway. The cables are obviously called cables. The supports underneath on the sides are called abutments, The foundations are located under the ground on the…

balance on the balance beam, since then I have provided you with plenty of opportunities to develop this skill further. My goal for you was to be able to walk unaided across the balance beam without holding my hand. I know you can do this as you have amazing gross motor skills, just look at the photos I captured of you whizzing down the pole. I think you just lacked confidence in yourself on this apparatus. Over the last few months I have set up vagarious different balance beam courses for…

Hitching a Ride on a Light Beam Physics is the most fundamental of the sciences, undergirding astronomy, chemistry, geology, biology, and—absent some paradigm-shattering revelation—human thought and action. Its analytical methods and machines have plumbed the unknown and the inaccessible, from the submicroscopic confines of the atomic nucleus to the billowing expanse of the observable universe. Physics has superseded our biochemically mediated perceptions of the world, replacing qualitative…

“alien abductions” where there’s the beam of light that draws the person up into the ship, or in Star Wars, the beam that can dock spaceships? That thing you’re thinking of is a tractor beam. Tractor beams are possible, but they are not yet advanced to the extent of Star Wars or alien abductions. The theory is that beam can reel a particle in towards the source. Currently, there are three types of tractor beams, sonic, light, and laser beams. So far, each kind of beam has only been created to…
