Introduction: The purpose of the Boomilever Project is to build a cantilevered truss that is light-weight while still able to support 15 kilograms. With this project it serves to reinforce the cumulative concepts that have been taught throughout this semester of Engineering Statics. It has been necessary to research designs, types of wood, and types of adhesive that will create a final result that is consistent with the desired result. Literature Review: The design concept behind a cantilever truss consists of a series of triangles joined together. The strength of these individual triangles, when combined, creates a very strong final result. Triangles are a very important part of many types of construction as they are the “only geometric figure that cannot be pulled or pushed out of shape without actually changing the length of one of its sides” (Bridges - Trusses, n.d.). As well as the advantage of the added strength, truss also do this without much additional weight. These concepts combined allow for trusses to be a very efficient way of adding strength. A cantilevered beam is what of which is supported on one end (usually a fixed support) and end is left hanging on the other end (Hibbeler, 2014). Cantilevered beams are able to support a load on the free-end. Cantilever trusses are popular in bridge and building architecture and possess many different uses. A cantilever truss with only a fixed end and a free end supporting a load and the negative y direction will translate the load across the supporting cantilever member and will thus have a positive y reaction at the fixed support since the sum of all reactions in a truss must equal zero (Hibbeler, 2014).

    One of Roebling’s greatest implementations in the Niagara Falls Bridge was his lattice truss design. Unlike the standard lattice truss systems where the diagonal beams lie over each other, his system interlaced the diagonal beams. This provided the structure with a higher rigidity than what was previously possible using traditional methods. This design was not flawless, however, as it substantially reduced the effectiveness of the diagonals. Roebling thought this compromise was acceptable given that the bridge supports served to buttress the system. Another advantage of the diagonal iron bands is that it avoids wooden joints which are comparatively movable and reduce the resistance of the system. A horizontal giving way (buckling) of the truss level is not possible since at the final point the vertical poles take only pulling tension…

    The first being that both the top and the bottom chords for the anchor and cantilever arms of the bridge were mostly designed as straight pieces. This was done to make the construction of the bridge easier and cheaper. The top chords that attached to the anchor and the cantilever arms on the Quebec Bridge were created to be slightly curved, because the engineers believed it looked more aesthetically pleasing. However, the curvature of the chords added to the secondary stresses on the members, and reduced their buckling capacity. The engineering records for the building of the Quebec Bridge has stated in it, “As a rule secondary stresses are much more dangerous in tension that in compression members, which seem to have been the first to give way in the Quebec…

    Method of joints: In this method, free body diagrams of adjacent joints of a member are seen to check the forces acting on different members. Also, “the first joint selected must have two unknown forces and one known force” (Walker 139). The unknown forces are later solved by using ∑x = 0 and ∑y = 0 (Since the whole model is at rest, it is considered that each member in the model will be at rest too). Once the two unknown forces are found, they become known forces to other adjacent joints and are used to find other unknown forces of another member. This technique is used on all the members of the model is found.…

    Deflections of a beam are important to be able predict the amount of deflection for a given loading situation. This experiment addresses determining the yield point for a material to fail, so the stress in the material does not have to reach to that point. This is where understanding beam deflection becomes a useful tool. This experiment is using beam deflection theory to evaluate and compare observed deflection per load values to theoretical values. Beam deflection experiment done by four parts. Part 1 -Simple Supported Bean, part 2-Cantilever Beam, part 3-The Principle of Superposition, and Part 4-Maxwell’s Reciprocity Theorem. For part 1 and 2 beam dimensions were recorded and are moment of inertia (I) was calculated using the following formula I=bh3/12.for part1, maximum permissible loads for mid-span and quarter-span were calculated. For part 2 maximum permissible loads for mid-span and end of the cantilever beam were calculated. For both parts different loads were applied and deflections were recorded. After calculating average modulus of elasticity for simple supported beam, which was approximately (-27.6*10^6 psi), it was compared to modulus of elasticity chart. The result indicates that the beam simple supported beam was made of Wrought iron. For cantilever beam, average modulus of elasticity were calculated, which was approximately (9148056.3), and compared with young’s modulus chart .the result indicate that cantilever beam was made of Aluminum. Part 3 reference point was chosen, single concentrated load at other point was applied and deflection was recorded at reference point. Same procedure was applied at another point on the beam and deflection was recorded at reference point. Finally, both loads were applied and deflection was recorded at the…

    The member forces of a truss can be calculated if 2J=M+R where J is the number of joints, M is the number of members, and is the number of reaction forces. It will only be stable if this equation is true for the values of J, M, and R in a given truss follow the equation. If 2J is greaer or less than M+R, then the truss will be…

    The Pratt truss was first developed in 1844 under patent of Thomas and Caleb Pratt. Since the 1840s through the early twentieth century, the Pratt has diagonals in tension, verticals in compression, except for the hip verticals immediately adjacent to the inclined end posts of the bridge. Pratt trusses were initially built as a combination wood and iron truss, but were soon constructed in iron only. The Pratt type successfully survived the transition to iron constructions well as the second transition to steel usage. The Pratt truss inspired a large number of variations and modified subtypes during the nineteenth and early twentieth centuries…

    Lastly, we built a truss bridge, one of the strongest and most efficient bridges. Tim, Goldium, Parker, and Nigel’s bridge had the lowest structural efficiency of 40. Even before we tested their bridge, it was wobbling on the table. I think their bridge was weak because they only had thin rods as support. Also, they didn’t include many triangles, choosing to use cubes at the top.…

    The reason the truss is so effective is because of the way it handles the weight. When there’s force being applied the force goes down the triangles and into the wide base. Considering the base of the truss is wide it is hard for the bridge to break. Also because in a triangle the the edges aren’t vertical like in a square the force makes the edges go wide which they already are so it isn’t that hard for the triangles to bear the…

    Truss Bridge Advantages

    • 680 Words
    • 3 Pages

    Truss bridges have many advantages that make it more useful for everyday use. The truss bridge is very economical to build and uses very few resources. It uses light materials and small loads of timber or whatever it is being made of. It is also one of the stronger bridges that can be built. The trusses on top of the bridge make it very strong because the triangle shape takes away much of the pressure and spreads the pressure to the triangles and takes it away from the road part of the bridge. The bridge is also one of the few designs that roads can be directly placed on top of. The truss bridge can also be built virtually anywhere, meaning it can be short or long and it will still be strong. It is also very easy to build. The truss…

    The Flavian Amphitheater, better known as the Colosseum, is regarded around the world as a marvel of architecture. The structure was viewed as a symbol of the Roman Empire’s wealth and power and was even featured on ancient roman coinage (Coarelli 175). A symbol not only of imperial pride during the Roman Empire, the Colosseum is now viewed as a symbol of the city of Rome and the nation of Italy and is even featured on Italian Euro coins. The amphitheater was not the first amphitheater created, nor the first in the city of Rome, rather it is revered for its sheer size. The massive amphitheater, which took ten years to construct, required over two hundred ox carts a day of eight by three foot blocks of travertine, tufa, brick, and iron.…

    In order to create the bridge it was essential to come up with a design which would be the most suitable to sustain the highest load possible. After some research, it was concluded collectively that to make the spaghetti bridge the spaghettis were shaped in triangles as it would make the bridge more stable, rather than using squares. It was also decided that the triangles would be done in a taller manner.…
