Undoubtedly the most important topics in this research are structural analysis, finite element methods and the basic review on Abaqus software due to the fact that this software is used as a research tool for examining the behaviour of structures. Therefore, it is essential to know about these topics and the relationships between them. An effort is made to review the important structural analysis and finite element method approaches, reports and fundamentals guiding the structural analysis of the CNC machine research in a coherent way, along with a few relevant examples from literature.
2.2 STRUCTURAL ANALYSIS
According to Mike N.Thomas, “structural analysis can be described as a physical law and mathematical calculation required for the prediction of the behaviour of any structure” (Thomas M. N., 2005). Indeed, structural analysis must put forth some other aspects that cannot be treated in a precise manner such as sound working patterns, conservation design and the concept of safety. The term structural (or structure) implies not only civil engineering structures such as bridges and buildings, but also naval, aeronautical, and mechanical structures such as ship hulls, aircraft bodies, and machine housings, as well as mechanical components such as pistons, machine parts, and tools (ANSYS PRODUCT). Although structural analysis uses the analytical methods for predicting the structure behaviour, regardless of those methods the formulation is based on the same fundamental relations such as equilibrium, constitutive and compatibility.
Galileo Galilei, Robert Hooke and Issac Newton were pioneers of modern structural analysis in the 17th century with their scientific works. The beginning of structural analysis was in 1638 when Gal...

2.3.1 BENEFITS OF FEM
However there are so many benefits that can be described for FEMs, but the most important benefits of finite element methods can be classified as follows:
• FEMs help tremendously in producing stiffness and strength visualizations in a structural simulation and also minimizing weight, materials and costs (DS.SIMULIA, 2007).
• It can show the critical area where structures bend or twist and also can visualize the distribution of stresses and displacements (Miodrag Skolowich, 2006).
• It can visualize the engineering design for many industrial applications.
• Other benefits of FEM can be mentioned as an understanding about critical design parameter, virtual prototyping, faster and less expensive manufacturing process. Clearly FEM allows designs to be constructed, refined and optimized before the design is manufactured (Bhushan, 2010).
We use metals to construct all kinds of structures, from bridges to skyscrapers to elevators. The strength as well as durability of materials that are crafted out of metal make the materials ideal not only for construction but also for many other applications.
According to Suspension bridges: Concepts and various innovative techniques of structural evaluation, “During the past 200 years, suspension bridges have been at the forefront in all aspects of structural engineering” (“Suspension”). This statement shows that suspension bridges have been used for over 200 years, and that people are still using them today because they are structurally better bridges. This paper shows four arguments on the advantages of suspension bridges, and why you should use one when building a bridge. When deciding on building a suspension bridge, it has many advantages such as; its lightness, ability to span over a long distance, easy construction, cost effective, easy to maintain, less risk

Laws such as the lever law and Euler’s Buckling Theorem come into play when testing and competition begins. A structure of wood and glue surely has much more to offer than meets the eye.
Mechanical engineering is a wide subject with many definitions and qualities about them. A mechanical engineer uses the principles of energy, materials, and mechanics to design and manufacture machines or devices (“Mechanical Engineering Overview”). Another definition that furthers the idea of a mechanical engineer is they research, design, develop, manufacture, test tools and engines (“Mechanical Engineering Overview”). They not only design the tool or devices for customers, but they may also design them for other engineers to help do their job (“Mechanical Engineer Job Description,”). A mechanical engineer is also involved in the mechanisms and methods by which energy is used for practical purposes (Mechanical Engineer Job). A mechanical engineer must have a variety of qualities that are associated with them, as their job varies on daily or weekly basis. One quality a mechanical engineer must have is being strong in math and science, as most of their work deals with thi...
When it comes to structural failure due to the collapse of a component, or a group of them, it refers to the deficiency of the part to withstand the stress of the workload for which it is designed. The components which an airplane is made of, are individually selected and thoroughly tested by manufacturers in such a way as to ensure safety standards of exceptional level.

The structural engineers use geometry in their design in order to calculate the spacing of their columns and beams for proper strength for the building.
Structuralism is a hypothetical school and basic development of the twentieth century, which showed up in the investigation of language, literature, art, human sciences and social science. It inquires about relations between essential central components in the specified, and in addition some other academic disciplines.

We have reached a point in time where the antediluvian ways have either been completely forgotten or are simply ignored for loss of necessity. This fast progressing world owes everything to the researchers and innovators responsible for the ever changing paradigm of technology. My capability as an engineer, however, to be truly able to understand how the various design aspects behind each innovation, helping me ponder over the numerous ways in which it can be implemented for technological betterment is what makes me stand apart. Right from my childhood, I have been fascinated by bicycles, motorcycles, cars, mechanical structures and basically anything that had virile relations; this was mainly because of the automobiles and other vehicles in movies that always used to drum in a sense of amazement that used to reverberate in my memories long after. It was only a matter of time before I came to realize the sheer brilliance behind every design, the immense perfection engineers strive to achieve and the amount of hard work and dedication required to impeccable levels in the whole process. I wanted to be a part of it and it was then that I decided what was worth doing with my life. I chose Mechanical Engineering as my major in my Undergraduate study and frankly, the field never ceases to amaze me.
Like all engineers, architectural engineers apply the theories and principles of science and mathematics to research and develop economical solutions to technical problems. Their work is the link between scientific discoveries and commercial applications. Engineers design products, machinery to build those products, factories in which those products are made, and the systems that ensure the quality of the product and efficiency of the workforce and manufacturing process. Engineers design, plan, and supervise the construction of buildings, highways, and transit systems. They develop new materials that both improve the performance of products and help implement advances in technology. Engineering knowledge is applied to improving many things, including the quality of health care, the safety of food products, and the efficient operation of financial systems.
