Strength of Materials - Essay Example Braun (2006) claims that elastic structure deformation when under a certain load reduces the maximum potential strain energy as per the virtual work principles. The deformed structures strain energy relies mostly on the load applied as well as on the structural design of the whole body. With prescription of the elastic properties of the structural members, the topology and the load exerted on the structure, the strain energy of the structure under particular load becomes a function of the nodal co-ordinates of the undeformed structure. To enhance the rigidity of the structure the nodes can be relocated in a particular way to reduce or minimize the strain energy. Material or configurational forces which maintain the shape of a particular structure are achieved through deriving the strain energy regarding the nodal coordinates. These forces when released make the structure take a shape with less or minimized strain energy thus the structure gets more rigidity. Some nodes require to be fixed because of constructional purposes for the optimization of the process. The support and applied loads locations can not be altered. The analysis of strain gauges gives a significant benefit to functional structures by directly assessing the state of resistance and movement of a particular structure in the mechanical environment where it runs. ... They are also applicable where the assumptions of simple shape of a certain structure defined loading of theoretical analyses are hard to obtain thus the strain gauges can be employed to provide significant information pertaining these. The strain gauges are useful to finding several functional analyses and information regarding performance of individual beams which leads to functional interpretations of structural design (Swartz, 1991). Strain gauges are gadgets used for measuring distance changes between several points in solid bodies when they experience some deformations. Work done in producing deflection of the body produces strain energy that is deflected in the strain gauge. They get information which is used in finding the stresses in those bodies or indicate and measure quantities such as pressure, force, electrical resistance and acceleration. They exhibit a change in resistance that is proportional to the mechanical strain exerted in the bodies. Most common strain gauge includes the insulating flexible backing that gives support to a pattern of a metallic foil. It is attached to the body and deforms as the body deforms leading to electrical resistance due to the alteration which is measured with the use of a Wheatstone bridge that relates the strain to a quantity termed as gauge factor. The gauge factor, Given, Refers To the Undeformed Gauge Resistance =Change in Resistance Due To Strain andStrain Metallic foil gauges have gauge factor a little more than two. Given, BV-bridge excitation voltage. Gauges used in measuring temperature variations detect change in size of the object due to thermal expansion as a strain and indicates in the gauge. This causes the

Business and Writing - Research Paper Example The purpose of this report was to evaluate the factors that must be considered before expanding the business on foreign soil. To evaluate the factors, the study focused upon taking the scenarios of other electronic organizations that geographically expanded their business without any difficulties. The thorough investigation of similar businesses led to an understanding the organizations must consider opportunities and growth prospects before expanding outside national borders. This can be clearly witnessed through the expansion of Sony. Not only did Sony focused upon the opportunities, but the company also held the confidence to succeed in the given market conditions. On the other hand, the case of Telefonica revealed that rather than focusing upon the opportunities, the Spanish company focused upon evaluating the similarities within the institutional and cultural characteristics in Latin America. Once it understood that both the countries shared similar characteristics, it expanded internationally despite the several criticisms against the geographic expansion. Lastly, the case of Mouser Electronics revealed that the evaluation of demand must be considered before expanding the business internationally. ... The products offered by the company have significantly enhanced the convenience factor of the customers, while providing the customers with additional value in their lives. To continually remain ahead of the competitors in the electronic market, Company G has always focused upon the offering of its competitors (i.e. the leading companies). This is primarily done to provide the customers with the best possible alternative in the market at comparatively lower cost than others. By assessing the tremendous demand of mobile phone and smartphone chargers in the market, Company G has introduced its own brand by the name of ‘ChargeOn’. The specialty of this charger lies within its convenience and small size. Within just half an hour, ChargeOn can charge any mobile or smartphone battery completely, while ensuring the maximization of battery life to significant level. Similarly, ChargeOn is a special charger that is water resistant. To perfectly meet the demand of the customers in the electronics market, the charger will be available in three ranges; standard USB jack, micro USB jack and mini USB jack. With outstanding opportunity to expand geographically, Company G has selected Canada for the expansion. The objective of this assignment is to evaluate the expansion of the company into Canada’s electronics market. To do so, the cases of other electronic organizations are taken into account to assess the factors that were considered before the expansion. A total of three cases have been evaluated. This has helped in the evaluation of best practices and factors that must be understood to significant level. The assessed information will then be used to help Company G to expand geographically to meet the needs of the customers through
