...------------------------------------------------- Balancing of rotating masses The balancing of rotating bodies is important to avoid vibration. In heavy industrial machines such as gas turbines and electric generators, vibration can cause catastrophic failure, as well as noise and discomfort. In the case of a narrow wheel, balancing simply involves moving the centre of gravity to the centre of rotation. For a system to be in complete balance both force and couple polygons should be closed. ------------------------------------------------- Static balance Static balance occurs when the centre of gravity of an object is on the axis of rotation. The object can therefore remain stationary, with the axis horizontal, without the application of any braking force. It has no tendency to rotate due to the force of gravity. ------------------------------------------------- Dynamic balance A rotating system of mass is in dynamic balance when the rotation does not produce any resultant centrifugal force or couple. The system rotates without requiring the application of any external force or couple, other than that required to support its weight. If a system is initially unbalanced, to avoid the stress upon the bearings caused by the centrifugal couple, counterbalancing weights must be added. This is commonly done, for example: in the case of an automobile tire, where the imbalance is due to imperfections of manufacture that make the tire composition inhomogeneous Rotating...

...a woman sold roasted chestnuts. It was warm, standing in front of her charcoal fire, and the chestnuts were warm afterward in your pocket. The hospital was very old and very beautiful, and you entered a gate and walked across a courtyard and out a gate on the other side. There were usually funerals starting from the courtyard. Beyond the old hospital were the new brick pavilions, and there we met every afternoon and were all very polite and interested in what was the matter, and sat in the machines that were to make so much difference. The doctor came up to the machine where I was sitting and said: "What did you like best to do before the war? Did you practice a sport?" I said: "Yes, football." "Good," he said. "You will be able to play football again better than ever." My knee did not bend and the leg dropped straight from the knee to the ankle without a calf, and the machine was to bend the knee and make it move as riding a tricycle. But it did not bend yet, and instead the machine lurched when it came to the bending...

...Baumol (1967), many years ago stated that productivity improvements in services are harder to achieve than in goods producing industries. There is no exact data about this but only some notion of hypothesis by the economists and business men support Baumol that it is hard to improve productivity in service sector due to some reasons. Service industry means one is offering their service using a platform and most commonly used platform till today is the labour force. The first reason that leads to the difficulty in improving productivity of a company is because service industry typically needs the intensity in their labour force to compare to the manufacturing industry. This is because the labour will deliver their service to the customer. They tend to involve a significant amount of customization or customer interaction, so their operations rely heavily on these labours. The more services to be delivered or the more customers to be reached, the more labour force will be required which then, costly per each labour salary they need to pay. For example, Hotel industry is labour-intensive since they need to hire more labours to satisfy their customer since they are delivering intangible goods to the customers and the only important platform of delivering that service which is the labour, must be qualified and enough. Talking about the importance in delivering the service to satisfy the customer, this is said to be the other reason for its harder to improve the productivity in...

...Manufacturing Company Case & United Machine Workers Introduction to the case analysis The legal aspect of every contract in business requires critical analysis for every term in accordance to the specifics upon which both parties are involved. The reason for analyzing such terms carefully is because it can become a crucial part in determining the decision making when addressing any business problem. This is generally more important from the perspective of the company management because some situations can result in high intensity and significance for the company. Analyzing the terms of a contract will help avoid any inappropriate or insufficient conclusions when presenting a final resolution in times of a dispute. The case to be evaluated in this assignment is the result from an opposing perception of an issue in which both party’s are involved. The grievance is the result from the opposing views on a subordination matter; that of the management’s perspective and that of the employee. The case to be evaluated can very easily occur in an actual situation and I would like to write this analysis from the management’s perspective. Summary of the issue(s) The problem involves the contradicting views of a legal issue within the union contract reached between our firm, the Acme Manufacturing Company (the company) and the United Machine Workers Union (the union). The parties in question in the dispute are Mrs. Kyla Martin, a machine operator working in the company and...

...efficiency of robots, but eventually a depressed job market would lead to a population that struggles just to feed themselves and their families, let alone purchase the products these robots make. In the long run, society will suffer if it does not take care to prevent the economic consequences of giving everything over to machines. Our careless use of automation has already taken a toll on our culture. People have been interacting with automation in nearly every aspect of their lives, whether it be shopping, banking, or the use of a telephone. The effect of this is obvious: basic respect for our fellow man is all but absent today because of increased interaction with automation. Why treat a machine with kindness? It suffers no emotional or psychological damage. In a culture saturated with automation, we get used to treating machines rudely, and we begin to treat each other rudely. This of course leads to all sorts of issues, like intolerence and incivility, and in the long run, results in the complete degradation of culture. Even in the face of these obstacles, some people argue that the increasing intelligence of today’s machines is a good thing. After all, machine power can decrease the human work load....

...tobacco (lamina) is moistened, cut and dried. Some of the excess stem produced in National Leaf is also used. It is fed into a conditioner using auto feed. Then, it is cooled and stored in silos to be processed further when necessary. A stem roller is used to flatten the stem so that it is ready to be cut first by the cutter and then by a millicutter. It is moistened using steam in low pressure and dried to attain the desired level of humidity. At this point the lamina and stem come together in the mixing cylinder where chemicals are added. There are different silos for each blend and the cut tobacco is stored in these. Four Rotary feeders are involved in transporting this to the secondary manufacturing department.

...Should machines be used to do good and services instead humans? I believe they should not for many reasons. Machines can not be smart unless a human is controling it. So it would not matter if its an intelligent machine or not a human is still controlling it to do everything. When using a machine it could easily malfunction and it could be hard to fix the problem or it will just take a while to fix it. If a human is taking over instead of the machine there may be fewer problems. Machines have so many problems that it would not be worth having. Also, the more machines you have the less jobs there are for people because everyone thinks it would be better to have machines instead of people. When less people are out of work that means less money for those people and sometimes they will lose their homes or cars because they can not afford anything. Sometimes working with machines can be very stressful because they may not work at times or they could be running extremely slow and won’t get anything done. Machines are not smart at all, only when people are controlling them they are but not all the time. It may seem smart but its really not. In conclusion, I think machines should not be used to take over a human job because machines can not think only humans can think and make right or wrong decisions. Machines do not have brains, their not wired to think so why have them do stuff that we can do...

He announced that we would arrive in only a few seconds. There it was Fort Brass; surrounding was a high fence with a bobbed wire curling at the top. We checked in through the gates there were guards surrounding the perimeter. Jones parked the truck told me to get out and walk in the metal building to the right he would meet me there shortly. I nodded in agreement, Jones then darted off to go park the truck. I proceeded to walk over to the large building when I opened the door I was stunned. It was a time travel machine about the size of an elevator. I heard rumors about the military building one but I never thought it was true.
