Truss engineering is the design and creation of trusses that are made of one or more potential materials. Trusses are crafted from a straight and slender pieces of material manufactured then connected at various joints to form a triangular shape. The common purpose of truss is to construct a large structure with the shape and design of truss adding strength and weather resistance to the overall structure(Šimi & Ilijaš, 2012). Truss can be designed as planar trusses, which are a two dimensional shape that commonly used in roofs and floors while space trusses are three dimensional shapes. Multiple trusses can also be combined.
Some consultant or engineering firms design and build pre-made trusses to be sold to construction and architecture

However if there are significant forces out of plane, then the truss should be modelled as a three dimensional to solve the truss analysis. In structural analysis, there exist several methods to analyse truss such as method of joints, method of sections, graphic statics, finite element method, etc.
The method of joints applies the equilibrium of joints and act as the basis for all truss analysis directed towards finding the unknown forces in the truss structure. Basically, a truss composed of a series of members and joints. Member’s forces are discovered considering all the joints or points in a state of equilibrium. Therefore for plane truss, the two independent equations of statics exist for concurrent force system (∑Fx=0 and∑Fy=0). The joint will move if there exist net force acting towards the joint. In addition, the method of section is applied by separate the truss structure into sections, and then replaces the removed section with unknown member forces acting in the direction of the cut member. The forces in the members are calculated by summation of unknown forces by using equilibrium equation∑Fx=0, ∑Fy=0 and∑M=0. Hence with only three equilibrium equations, the truss section cut should be located where there are only three unknown member

The Engineering of a Trebuchet To understand all the works and Physics behind a trebuchet, you must first understand all the individual parts of the trebuchet. Corresponding with most machines, the trebuchet is made up of different parts each having their own unique function. The five parts of the trebuchet are; the frame, the arm (or beam), the counterweight, the sling, and the guide chute (“How the Trebuchet Catapult Works”). Additionally, corresponding with most machines each part of the trebuchet can manipulated to create a different output.
The amount of triangles a truss has varies among all of the truss bridges out there, but does the amount of triangles that a truss bridge has impact the amount of support it provides? People used
Military bearing is the start in which every soldier practices either as enlisted or commissioned in order to have good discipline and ethics throughout a military career. Army regulations and soldiers should live by the creed that a military service member should conduct themselves on a daily basis, on and off duty . Loyalty, Duty, Respect, Selfless Service, Honor, Integrity and Personal Courage are Army core values. To be a dependable Soldier you must show your NCO’s that you can be an adult with time management, meet deadlines, be in the right place at the right time, in the right uniform, and doing the right thing at the right time. Dependability is a major aspect of military bearing.
The chapter "Too Heavy to Lift", from the Thomas King novel The Inconvenient Indian, differentiate three categories of "Indians", namely Dead Indians, Live Indians and Legal Indians. These categories are social constructs from the Western settler world. I thought the Living Indian analysis was interesting, as it talks about Indigenous people never being Indigenous enough in the settler's eyes. The Legal Indian category raises the important question of the status. In his text, King implies that "only about 40% of Live Indians in North America are Legal Indians".
The trouble with this is that clients don’t see architecture as a service based industry and perceive it as a product based industry, the product being a set of deliverables, consisting of drawings documents and specifications, In this instance it becomes easier to for the client to appraise architectural fees, they can measure the deliverables against the price. The reality is that the set of deliverables are product of the architectural service they are a expression the clients briefing
Also, a structure must be designed with redundancy to prevent “progressive collapse”, a failed part of the forces must be able to reroute to another path, which means the structure must be redundant. In this case, if the structure with additional bars provided would increase redundancy then the load would have been transferred to the additional bars instead of just one adjacent eye-bar which resulted in failure of the whole eye-bar chain. Other than that, non-destructive inspection methods was studied after the collapse, to ensure all bridges which will be built later can be easily for inspection and
The measured tensions were normalized relative to the maximum tension and the lengths were normalized relative to the length at which maximum force was generated (Ln = 29 mm). The measured data and expected data were plotted together (Figure 3). Correlation between measured and expected tensions at the same normalized lengths was determined for the three expected segments of the length-tension relationship.2,3,4 This was done using piecewise linear regression and yielded r2isometric = 0.956033. The fitted curve for the isotonic experiment resulted in r2isotonic = 0.960557. The F0 was 19.5 N for the fit and 6.35 N for the guess.
Welding is a great job but not many people know what welding is or how it work. According to Thomas net welding is the process of joining metal together with heat welders can work on many kind of structures such as mobile homes, pipes, steel reinforcement and others. Because welding is a relatively easy manufacturing process and provide a great deal of strength (Thomas).To become a welder you need four skills the first skill you need is problem solving because welder must be exceptional problem solver who pay attention to details. They have to spot flaws in materials and designs troubleshoot broken areas and know to fix parts or equipment. The second skill math and science welders constantly use their knowledge of fundamental science and math
I had first formal exposure to civil engineering in course “Architecture 1”. This course provided me the fundamental concepts of civil architectural principles such as designing procedure, architectural component’s layouts, functional spaces as well as environmental impacts. To strengthen my concepts I pursued the courses “Strength of Materials”, “Structural Mechanics” which gave me essential knowledge about the external and internal forces occuring in simple structural elements under action of various types of loading as well as fundamental concepts in structural analysis such as modellisation, classification of structures. I gained valuable exposure to the analysis of simple structures submitted to compound loadings by the application of the principle of superposition for such cases as: unsymmetric bending, combined bending and tension or compression, combined bending and torsion, general compound loading. Futhermore, I was fascinated by the force method and displacement method for analysis of statically and kinetically indeterminate structures.
Introduction Romanesque architecture started around 1000 to 1200 AD around the middle ages, extending from the decline of the Roman Empire until the begging of gothic architecture. It is one of the most influenced styles of architecture but also one of the most hard to characterize. Unlike other styles it developed independently in diverse locations such as Italy, Spain, England and France. Its characteristics come from the ancient roman architecture that developed into bigger prettier and more complex constructions. However, there are different views in where it spread first as well as where it got more influence from.
There are mostly two kinds of Roofing these days. First is the Commercial and other one is the Residential Roofing. Commercial Roofing is used to ensure and seal the highest point of commercial structures while residential roofing is for the security of the private houses and flats. It covers basic entries and avoids leakage of rain water from entering the building. Commercial Roofing by and large has a generally level slant, instead of Residential Roofing, which is regularly steeply inclined.
The structural strain theory was developed by sociologist Robert K. Merton as part of the functionalist perspective. Strain occurs when individuals find it hard to achieve cultural goals through institutionalized means (Merton, 1938). This theory suggests that there are five responses to strain, which include conformity, ritualism, innovation, retreatism and rebellion (Andersen and Taylor, 2009). The responses are developed based on two factors, which are, first, whether the individual accepts or rejects the cultural goals of the society and second, whether the individual accepts or rejects the instituitionalized means of achieving them. To understand this theory, we first have to understand what cultural goals and the institutionalized means of achieving them mean.
