The Motif of Blades

- Many authors use symbolism to convey messages about society as a whole. One particular symbol which is trans-cultural and appears in much of literature is that of the blade. The blade in many cases embodies masculinity, honor, and courage. In the two stories “In a Grove” and Chronicle of a Death Foretold the authors use the motif of the blade to convey similar messages about the societies in which they take place. Both authors Akutagawa and Marquez use the motif to give an insight into views of honor and masculinity in the societies of Japan and Latin-American countries, respectively....   [tags: In a Grove, Chronicles of a Death Foretold]

The Use of Turbine Blades in Generating Electricity

- The Use of Turbine Blades in Generating Electricity Turbines are used in many different ways produce and generate electricity. They are used as gas turbines, coal turbines and steam turbines. Each one has a different property, which makes it unique. Airlines and cars generally run on gas turbines. Steam engines, ships and railway engines run on coal turbines as coal produces a high amount of energy that enables them to run for long length of time before adding more coal. In order for these turbine's to operate well and efficiently with as little maintenance as possible, it is necessary for the turbine's to have well-constructed, well designed turbine blades....   [tags: Papers]

The Importance of Wind Turbines for Renewable Energy

- ... Low-mass materials are also ideal in order to control blade weight. [5] Larger blades with larger weights are constrained by gravity and will experience greater axial and tensile stresses. Finding the best size and material for rotor blades depends on the purpose of the turbine. Smaller power demands will reduce the need for larger blades and taller turbines. Linking the rotor blades to the electrical generator is the turbine shaft. When the rotor blades spin, the shaft spins as well.

Ice skating is a make it or break it sport. Only a sharp thin blade separates this person from direct contact with the ice. The edges are there to guide, the toe pick there for balance, and the hollow there for when a person feels brave enough to test their luck in the hopes of accomplishing a spin or a jump....   [tags: Sports]

Out Board Propeller Dynamics

- Missing Figures In The fall of 2004 I purchased a boat and outboard. The company that built the boat also had the responsibility of mounting the out board. Unfortunately the company built the transom of the boat to high and this had a major effect on the boats performance. With the prop so close to the water’s surface the out board would ventilate ever time I tried to get the boat up on step. It would also ventilate on tight turns at high speeds. Unless I wanted to ship the boat back down to Seattle for modifications I would have to find a propeller that would operate effectively near the surface....   [tags: physics boat propeller]

The Sky is the Limit For Wind Power

- Owen Paterson said “The relationship between renewable energy sources and the communities we expect to host them must be appropriate and sustainable and, above all, acceptable to local people.” For that reason, environmentalists have long assumed that wind power is a much more efficient and sustainable way to generate electricity. However, non-supporters of wind power state otherwise because there are a few negative outcomes to using wind power. Ultimately, when it came to the nature of wind power the basic assumption was that it is beneficial to the environment and communities....   [tags: Renewable Energy Sources, Wind Power]
