Effects of wind-loading on bridges Wind Loading Wind is a word that used to describe the motion of the air. It is the natural phenomenon which caused by temperature differential that is resulted from solar radiation. A moving wind that comes in contact with a solid structure will be distracted. Although the wind structure is not fully stopped‚ it still loses some of its velocity. This is due to the frictional force faced by the wind flow and the surface of the bridge. This phenomenon is actually

Sailing is the art of controlling a sailing vessel. By changing the rigging‚ rudder and dagger or centre board‚ a sailor manages the force of the wind on the sails in order to change the direction and speed of a boat. Mastery of the skill requires experience in varying wind and sea conditions‚ as well as knowledge concerning sailboats. Today most people enjoy sailing as a recreational activity. Recreational sailing or yachting can be further divided into racing‚ cruising and "daysailing" or dinghy

3.7 Wind Generators: There are three main parts in horizontal axis wind turbines: (1) a rotor‚ (2) an alternator‚ and (3) a tail. The rotor blades are attached to a central hub covered by a nose cone that improves aerodynamics. Three blades are generally present in upwind generators. This entire assembly rotates when wind blows past the blades‚ hence the name “rotor.” In many small wind turbines the rotor is coupled to a shaft which is coupled to an alternator‚ a device that produces AC electricity

The wind farms were created to use for an alternative use to burning coal for electricity. “ It would do so without producing local air pollution or the greenhouse gases that causes global warming” (Layzer‚ 421). The wind farms are a good idea because it is a step to saving the environment instead of burning so much coal. It keeps the air from being polluted and is a step in the direction we need to make to finally make a change with the environment. “Cape wind could offset more than 1 million tons

The two types of energy resources I chose were wind energy and biofuel energy. Wind energy uses turbines which convert the kinetic energy in the wind into mechanical power. This power can be used for a generator‚ a generator can convert this mechanical power into electricity to power homes‚ businesses‚ schools‚ and many others. Biofuel energy unlike other renewable energy sources can be converted directly into liquid fuels for our transportation needs usually found from dead plants and animals

The Mandarin‚ an official in the Chinese Empire‚ says that the pig can devour the orange at any moment. This means that more people are going to show up
