Literature Review of My Dissertation - Essay Example Prior to the international disaster setting in, it was flourishing and was considered to be Turkey’s trademark and a proof of the active role it played in world economic trade scenario. â€Å"The Turkish shipbuilding industry has made a considerable contribution to the Turkish economy with 1.5 billion $ from new ship building, 1 billion $ from repair and maintenance activities. Furthermore, industry creates an employment opportunity to 25,000 people directly and 100,000 people in total with related industries. In 2007, 98 ships with a total of 670.000 DWT were delivered. 80 Ships and yachts were already contracted for 2008. Over the past three years, Turkey has gone from being the world’s 23rd largest shipbuilder to being 8th on the list.† (Tulay Uyanik) It was truly global in its reach and remained commercially lucrative and profitable for a very long period of time till the worldwide financial recession gripped this business too in its vicious claws. Mr.Zaman, Minister of Transport Binali Yildirim says, â€Å"The shipbuilding capacity has increased by an average of 65 percent in the last four years. The number of shipyards operating or about to start operating in Tuzla as well as in the Black Sea, Izmit Gulf, Yalova, in the Aegean or Mediterranean has reached 60. We used to build ships of up to 20,000 tons maximum but we are currently able to build ships of up to 60,000-70,000 tons.† (www.turks.us) The once-prosperous community of owners who were doing extremely well earlier are now facing a grim situation coupled with many challenges like the over-valued lira which is the currency of Turkey, an unexpected spurt in the overall costs of running the ships and large amounts of contributions made towards the social security benefits of the crew members aboard these active ships. The high costs of protecting the workers’ interests increased the maintenance

Estimation of the value of gravitational acceleration (g) Based on Lab Report

Estimation of the value of gravitational acceleration (g) Based on measurements from a simple pendulum - Lab Report Example derived value after factoring in the uncertainty, corroborating the insight that the time period of the oscillation is dependent solely on string length (Ji and Bell 2015; Jardine-Wright 2010). The experiment calls for the calculation of g or the gravitational acceleration via the use of a simplified mechanism, and then undertaking a comparison between the value arrived at from that mechanism with the standard value of g, which is pegged at 9.81. The key principle in the mechanism of the oscillation of systems such as the simplified pendulum lies in being able to grasp the nature of the forces that act on the mechanism. In the pendulum, it is the force of g or the gravitational acceleration which impinge on the frequency of the oscillations, effecting a dampening effect on those oscillations through time. The oscillations of the pendulum mechanism can be construed as being simple harmonic in nature and is periodic. Here the force of restoration is in direct proportion to the pendulum displacement. For the purposes of this paper, the relevant formula is the one that prescribes the value of the time period, which is given thus (Ji and Bell 2015; Jardine-Wright 2010): In the equation above, the value of T is dependent only on the string length l and g. Therefore, given T and l, g can be derived. The insight from the experiment is in being able to understand the way the oscillating system variables affect each other, as stated in the instructions; how the value of g is derived; and what the measurement errors and the causes of those errors are (Ji and Bell 2015; Jardine-Wright 2010). Two people made up a group, and the basic materials were the cotton rope, which was used as the string to hold the weight, which was first a plastic ball and later changed to a golf ball for more weight. The measuring devices were a ruler and an iPhone used as timing device. The rope was tied to the golf ball, and the time to ten oscillations were measured, with the golf ball suspended
