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…

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…

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…

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,…

Beam bridges, are also known as girder bridges. They are one of the oldest and most common bridges. They are held up by river banks or piers at both ends. Box girders and trusses can help a beam bridge stay up and be stronger. Highways overpasses are normally beam bridges. The first person to build a beam bridge is not known. Although, the first beam bridges were built in ancient times. Some of the first beam bridges were built in Rome. Some of the most famous beam bridges are the Manchac Swamp…

A beam bridge or known as a girder bridge, is a bridge structure that consists of horizontal beams spanning supported by pillar at each end of the deck. The weight of the beam including the structure itself, plus any load it carries are supported by the downward force into the pillars. The beam bridge works on the principles of compression and tension, where on top of the bridge bends, it undergoes compression and at the bottom it is subjected to a horizontal tension. Therefore, the bridge must…

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…

“She just sits there, staring at the wall. Sometimes she blinks and awareness flickers in her eyes as she sits up, but then it disappears and she sinks back into her corner.” “What does she do all day?” “Strokes a scrap of velvet. Screams, Cries. Thinks. Stares.” “What does she think about?” “Let’s ask her, if you’re so interested.” The two men walk into Jenna’s room, where she sits huddled in the corner, rocking back and forth. “Jenna, what do you think about all day?” She looks up at him, sad…

“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…

I started out both days of a busy weekend by running the Rugged Maniac course in Englishtown NJ. At this point, I have pretty much done most of the OCR’s that are on my bucket list to complete, but Rugged Maniac was one of the few left that I had yet to complete, so I was excited about this weekend and the chance to run the course on both Saturday and Sunday. • Festival / Spectator Area: I have participated in four other different events at this specific Englishtown venue and all but one have…
