Design Test Rig - Coursework Example In some cases, test rigs are designed depending on the equipment to be tested. One example of a commercial test rig is the Crash Test Rig designed and fabricated by JK Controls Limited. The apparatus comprises of a trolley that hauls the sample being tested. The trolley, which moves along a track by rotating rubber cords, is stopped abruptly by applying a decelerating force using a solid beam (JK Controls Limited, n.d). The test rig facilitates the determination of the required braking force of equipment, which is dependent on the weight of the equipment, braking materials and the speed. Another example of a commercial test rig is the Aircraft Wing Brake Test Rig designed and fabricated by JK Controls Limited. The rig tests the braking system of an aircraft by subjecting a rotating shaft (of a prototype) to a brake that is electrically operated. The shaft, which rotates at 1500 rpm, has to be halted by the brake within 40ms (JK Controls Limited n.d). The test rig being designed will operate on the same basic principle, the application of a braking force to a rotating disk to prevent it from rotating. At equilibrium state, the braking beam will be in contact with the surface of the disk (stationary). The contact action will be achieved through a locking mechanism. Once the operator applies a force on the braking beam, at the contact patch, the braking beam retracts from the disk, which allows the disk to rotate. The test rig will be used for determining braking force required to stop a rotating disk within a given time. Therefore, the applied force will be used to disengage the braking system to allow the disk to rotate. Once the operator withdraws this force, the braking system will be engaged. The basic operation principle of the test rig is similar to the Crash Test Rig and the Aircraft Wing Brake Test Rig presented above. However, the rig will contain several other components that will work together to achieve the ultimate goal, braking action. Concept

Security Administration and Management - Essay Example From our analysis, by focusing on differentiation strategies in the security industry, Securitas AB success can be attributed to its vast experience in the market, product differentiation, and assorted brands. Securitas AB by using its trademark experience and know how both product differentiation and cost leadership strategy means the company has a focus strategy, focusing on cash on transit and other security system. It business concept of ", packaging, counting and storage of physical values such as cash and precious metals". This has become part of the company's culture. According to Johnson & Scholes (2007), organisational culture is a tool in management strategic armory which appears to be invisible yet it influences "why" "how" "what" and "when" things are done in an organisation or "it is the way things are being done here" (Johnson & Scholes 2007:66 Today's business environment is increasingly becoming more turbulent, chaotic and challenging than ever before and to survive, it is vital that a firm can do something better than its competitors ( Wonglimpiyarat 2004:1). ... 1.0 Introduction Today's business environment is increasingly becoming more turbulent, chaotic and challenging than ever before and to survive, it is vital that a firm can do something better than its competitors ( Wonglimpiyarat 2004:1). Globalisation has not only altered the nature and the intensity of competition but has had to dictate and shape organisations in terms of what consumers wants, how and when they want it and what they are prepared to pay for it (Hagan 1996:1). Kanter (1995:71) on his work of "Mastering Change" argues that success in the present day business is not for those companies that re-engineer the way they do things, or for those fixing the past. According to Kanter (1995) such an action will not constitute an adequate response. This is so because success is based on an organization's ability to create, rather than predict the future by developing those products that will literally transform the way the world thinks and view it self and the needs (Kanter 1995:71). Within the context of today's global competition, businesses and firms no-longer compete as individual companies but try to corporate with other businesses in their activities (Wu & Chien 2007:2). These researchers went further to argue that, this strategy has become quite common in many businesses including the retail clothing chain stores. The conventional vertical integrated company based business model is gradually being replaced by collaborative relationship between many fragmented, but complementary and specialized value stars and constellation (Wu & Chien:1). This paper aim at examining the external environment of the United Kingdom Mobile phone industry, this
