...2.Evaluation of Business Environment (SWOT/5-Forces Model) 1. Evaluate the progress Cathay Pacific has made on outsourcing their IT activities. Do their ideas make sense to you? Why? 1. Threat of new entrants--LOW * Large capital requirements * Industry regulation * Technical requirements * Pilot shortages * Government control () The airline industry requires large capital and high technical. Also, there are a lot of regulations within the industry. And many government now put pressures on new start-up aviation companies, take China as an example, Civil Aviation Administration of China now do not approve to set up new airline companies. New entrants into this field would face large barriers. Thus, the treat of new entrants is low. 2. Threat of substitutes—Medium * International routes-shipping * Domestic routes Long distance bus Railway High-speed rail… In the international routes, the substitute for airline is shipping. In domestic routes, the substitutes are long distance bus, railway, and high-speed rail. Although, these would take more time to reach destination. However, they are cost- effective choices especially the high-speed rail comparing with airplane. High-speed rail is gradually operating in a large scale with convenience and comfort. There is a saying that in the future, once the airplane could reach, so could high-speed rail. So we judge the threat of substitutes is medium. 3. Bargaining power of suppliers—LOW ...

...ASSISTANT INVESTIGATOR: EXPERIMENT NUMBER: #5 EXPERIMENT NAME: Composition of Force EQUIPMENT: Force Table, Pulleys, Thread, Slotted masses, and Hangers. OBJECTIVE: To resolve a vector in to its rectangular components and to find the sum of the three vectors using both graphical and trigonometric techniques. Also, to check the validity of the computations by experiment. THEORY: Using Graphical and trig metrical techniques we should be able to find the resultants for vectors. If the given θ we should be able to use Ax=cosθ or Ay=Asinθ to find the length of a vector. If given Ax and Ay the use A2=Ax2+Ay2 the Pythagorean thermo to find A. When adding vectors simply use Rx=Ax+Bx+Cx or Ry=Ay+By+Cy. In part A, given a force of 0.981 Newton’s at 30 degrees. Then set up this force on the force table. In part B, Given the three forces F1 = 0:490 N at 0 degrees, F2 = 0:736 N at 30 degrees, and F3 = 0:589 N at 135 degrees. Then set up these forces on the force table. In part C, Using the forces given in Part B, compute graphically the components of each of the forces. Compute the vector sum graphically by laying them out head to tail.

...Experiment 31: Magnetism Purpose To study the relationship between magnetic force and the magnitude of the current, length of the wire, strength of the magnetic field, and the angle between the field and the wire. Apparatus SF-8607 Basic Current Balance (Main Unit, 6 Current loop PC boards, Magnet Assembly with 6 magnets), DC power supply, DC ammeter, Balance, Lab Stand, hook-up wires with banana plug connectors Theory A current-carrying wire generates a magnetic field surrounding the wire. When this wire is placed in an external magnetic field, it experiences a force due to the poles of the two magnetic fields interacting. The magnitude and direction of this force depends upon four variables: the magnitude of the current (I) in the wire; the length of the wire (L) that is placed in the external magnetic field; the strength of the external magnetic field (B); and the angle between the direction of the wire and the direction of the magnetic field ((). This magnetic force can be described mathematically by the vector cross product: Fm = I L X B, (1) for which the magnitude is: Fm = I L B sin (θ). (2) With the SF-8607 Basic Current Balance, you can vary the three quantities in (2), namely: I, L, and B. The resulting magnetic force between wire and field can then be determined through the simple calculation. By adding the SF-8608 Current Balance Accessory, you can also vary the angle between the...

...What is force field Analysis? Force field analysis is a management technique developed by Kurt Lewin, a pioneer in the field of social sciences, for diagnosing situations. It will be useful when looking at the variables involved in planning and implementing a change program and will undoubtedly be of use in team building projects, when attempting to overcome resistance to change. Kurt Lewin assumes that in any situation there are both driving and restraining forces that influence any change that may occur. Driving Forces: Driving forces are those forces affecting a situation that are pushing in a particular direction; they tend to initiate a change and keep it going. In terms of improving productivity in a work group, pressure from a supervisor, incentive earnings, and competition may be examples of driving forces. Restraining Forces: Restraining forces are forces acting to restrain or decrease the driving forces. Apathy, hostility, and poor maintenance of equipment may be examples of restraining forces against increased production. Equilibrium is reached when the sum of the driving forces equals the sum of the restraining forces. In our example, equilibrium represents the present level of productivity, as shown below. Steps involved in Force Field Analysis Step-1 : Prepare the statement of the problem or issues under study (note : make sure that the statement is indicative and provide clear understanding and perspective regarding the cause variables). Step-2...

...Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems, and countless other objects. This activity is based on Lab 4 of the eScience Lab kit. Although you should read all of the content in Lab 4, we will be performing a targeted subset of the eScience experiments. Our lab consists of two main components. These components are described in detail in the eScience manual. Here is a quick overview: * In the first part of the lab, you will measure the force it takes to pull objects of different mass. This experiment focuses on the effects of frictional forces. (eScience Experiment 1) * In the second part of the lab, you will investigate the effects of air resistance by performing controlled drops of coffee filters.

...oscillation depended on the effective mass of the spring and the period of oscillation. Students recorded basic information such as the position of the mass before the spring is charged, the path of the mass, the peak of the oscillation, as well as the force the mass and the spring exert on each other. Data studio and a force sensor, and a position sensor was used to get accurate measurements of these values. Goal The purpose of this laboratory is to characterize the oscillation of a simple spring-mass system. Theory If a spring is stretched or compressed a small distance from its equilibrium position, the spring will exert a force on the body given by Hooke's Law, where is known as the spring force. The constant, , known as the spring constant, and is the displacement from the equilibrium position. The spring constant is a clue of the spring's strength. A large value for indicates that the spring is strong or stiff. A low value for means the spring is weak or flexible. Springs with large values can balance larger forces than springs with low values. The negative sign in indicates that the direction of is always opposite the direction of the displacement. The spring force is a restoring force. In other words, the spring force always acts to return the weight or body to the equilibrium position regardless of the direction of the...

...Interaction (7 marks) Body parts move in a sequence to generate the largest force or accelerate possible. To sequentially produce a maximal force effectively, the following principles need to be applied: 1. The stronger and larger muscles of the thighs and trunk are moved first followed by the smaller and faster muscles. This is seen in diagram 1. 2. Sequentially accelerate each body part so that optimum momentum passes from one body part to the next. In the transition from diagram 1 to 2, we see this sequential acceleration of muscle movement. 3. Each body part should be stable so that the next body part accelerates around a stable base to transfer momentum. In pitching it is essential to adopt a wide stance to increase stability. This is done by placing legs further apart from each other. 4. Use as many body parts as possible, so force can be applies over the maximal possible time. The pitcher can increase number of segments by getting side on, whilst also uncocking wrist prior to throw. 5. Follow through is important to prevent deceleration of last segment and safe dissipation of force. This can be seen in the transition from diagram 3 to 4. 6. Ensure all forces are directed towards the batter (the target) b) Spin (6 marks) 1. As the pitcher is throwing a curveball, the type of spin is sidespin. 2. Diagram 3. At the commencement of the throw, an eccentric force is applied to the ball to cause...

Also, with the use of an in-house sales force, the company would have to reach sales of $18,600,000/year and this level wouldn’t be reached for at least one more year. Finally, the in-house sales force plan is highly leveraged, so when sales do reach $18.6 million, that leverage would assist the company quite a bit. So, at this point, till that 18.6 million sales goal is reached, the company should stay with the outside sales agents despite a 5% increase...

...the Bosnian War were the forces of the Republic of Bosnia(Bosnian Government Forces) and Herzegovina and those of the self-proclaimed Bosnian Serb and Bosnian Croat entities within Bosnia and Herzegovina,Republika Srpska and Herzeg-Bosnia, who were led and supplied by Serbia and Croatia respectively. The war came about as a result of the breakup of Yugoslavia. Following the Slovenian and Croatian secessions from the Socialist Federal Republic of Yugoslavia in 1991, the multi-ethnic Socialist Republic of Bosnia and Herzegovina, which was inhabited by Muslim Bosnians(44 percent), Orthodox Serbs (31 percent) and Catholic Croats (17 percent), passed a referendum for independence on 29 February 1992. This was rejected by the political representatives of the Bosnian Serbs, who had boycotted the referendum and established their own republic. Following Bosnia and Herzegovina's declaration of independence (which had gained international recognition), the Bosnian Serbs, supported by the Serbian government of Slobodan Milosevic and the Yugoslav People's Army (JNA), mobilized their forces inside the Republic of Bosnia and Herzegovina in order to secure Serbian territory, then war soon broke out across the country, accompanied by the ethnic cleansing of the Muslim Bosnian and Croat population, especially in eastern Bosnia and throughout the Republika Srpska. The Muslims were the people who were affected by the ethnic cleansing, but it was the Bosnian govt. forces that had an armed conflict...
