Report - Essay Example This is determined by the direction of the moment (Bansal, 2001). When the moment on the left of the force is clockwise and the moment on the right of the force is anticlockwise, the moment generated is considered positive. However, this causes the beam to bend and is also called the sagging moment. There are two types of loads, which cause moments on beams. These are either concentrated loads or distributed loads. Distributed loads have the weight spread over the significant length of the beam. However, the concentrated loads have their weight placed on one point of the entire beam. The shearing force in the beam is the chance that at that point, the beam is likely to slide laterally against the other portion of the beam. The diagrams below best explain the relationship between beams which have uniform weight distribution, their bending moments, and their shearing force distribution along the length. For a beam whose length is denoted as l with a distributed weight of w supported on both ends: The total weight acting on the beam is W*L= WL The reactive forces at both supports of the beam are obtained to be WL/2 (for each end of the beam) In order for the moments to be calculated, the force on the beam is assumed to be acting on the middle of the beam (L/2) (Bansal, 2001; Kassimali, 2010). The moments calculated about a point X length from the left of the beam, will be denoted as: (WL/2)*X – (WX)*X/2 = WL/2 * (L - X) The maximum shearing force will be WL/2, and the minimum shearing force will be –WL/2. There is no shear at the centre L /2. The moment is greatest here, according to the analysis. This can be found by replacing X with L/2 to give: M= (WL/4)*(L - L/2) = WLL/8 The ultimate limit state allows that the load allowed on the beam be 1.33*W, where W is the weight of the first plastic deformation of the beam. Thus, the initial load allowed on the beam, considering the ultimate limit state design, should consider that the beam is subjected to elasticity up to a certain extent (Kassimali, 2010). The solution W = 5KN + 1 KN = 6 KN L = 4000mm = 4M Shearing force: Wl/2 =6000N * 4m* 0.5 = 12000NM 12 KNM The maximum moment: WLL/8 = ( 6000*4*4) / 8 = 12000NM The ultimate weight allowed is, 1.33 * 6000 = 7980 N Question 2 The U-values are sum of all the thermal resistances of the materials used in the construction of the walls of buildings. This is also described as the sum of the inverse of all the thermal resistances in the materials used in constructing buildings. Thermal resistivity is a measure of a material’s property to fight the transfer of heat across a material, with a temperature difference across it. These values are obtained from already set British standards, published by the British Standard Institute. The units for this property are (m2k)/W. Fabric heat loss in materials occurs when there is a temperature difference between two different sides of that material. Due to the difference, the material experienc es a process of heat transfer from the hot side to the cold side. In the construction industry, it is important to obtain the heat loss values in order to know how to heat up buildings in winter, to a desirable temperature. The units for the U value are W/m2K, which is the reciprocal of the thermal resistivity (Yogesh & Jaluria, 2003). The thermal resistivity of the dense brickwork – 1.6 Thermal resistivity of wool batts - 0.048 Thermal conductivity of glass –

Case interpretation - Research Paper Example These scenarios provide a basic idea about the challenges which might be faced by the business environment in order to survive in the marketplace in the year 2050 (Deutsche Post AG, 2012). Among these case scenarios, this paper aims to evaluate the state of affairs presented in the first scenario, titled as Untamed Economy – Impending Collapse. Furthermore, the paper will assess the challenges which might be faced by the logistic industry due to the most probable challenges in the business environment of 2050. It will also intend to identify the reasons and/or causing factors of these challenges. Case Scenario: Untamed Economy – Impending Collapse The entire world is distinguished with the assistance of unrestricted materialism and consumption. In addition, the rapid growth of international trade set the pace of business and economy all across the world. The advanced global transportation also ensures the frequent exchange of goods and services all across the internatio nal territories and/or boundaries. With this concern, it has been observed that the world economy is forced by unsustainable standard of living along with the uncontrolled exploration of natural resources which in turn creates a string negative impact over the stability of business environment. ... It is most likely to be disrupted by the frequent natural disasters which in turn can have strong influences on the global supply chain increasing capital costs in terms of logistic companies. Apart from this, the international trade is also quite likely to increase the demand of production processes by the companies in the global dais. Therefore, rising insufficiency of energy resources, higher energy prices and costlier raw materials shall lead to slackened profit margin in the industry sector. With this concern, operational managers of the global logistic industry should actively response to the disasters with the help of contingency planning (Operations Manager, 2012). It has further been observed that operational managers are mainly engaged with inventory management processes, shipping and receiving as well as hiring and training employees in the current day context. However, in such probable scenario of 2050, an operational manager shall need to focus on inventory management al ong with strong networking of supply chain according to the regional divergences in order to maintain the profit margin (Johnston & Clark, 2012). Challenges to be faced by the Logistic Industry in the Year 2050 In the year 2050, the logistic industry might have to face various challenges in terms of supply chain disruption, high energy prices, expensive raw materials and shrinking profit margins. In the upcoming eras, there are high chances for scarcity of resources due to the natural disasters and frequent climate changes which in turn shall create the nationalism and protectionist barriers across the international boundaries. Additionally, this might come up with
