What are power lines?

A power line is a cable that carries electricity from a power station to the users of the electricity or between electric utilities in a network. The cables are passed from a tall steel lattice structure. Power lines are located high overhead or buried underground. So they do not get in the way of any human activity or are a threat to any wildlife. The wires are spread to prevent birds on perching on them and electrocuting themselves although all wires are surrounded by a layer of thick plastic as plastic is not a conductor of electricity.

About power lines

The power line frequency is extremely low as you can see from the diagram below

From the section ‘about power lines’ you can see that power lines produce a very low radiation, lower than radio. Hence do not damage people’s health dramatically. They produce a very low frequency so affect the human body little. There must be another factor causing diseases which hasn’t yet been discovered fully.

  1. Wind Power.

    This means that the wind must be fast enough to move the aerofoils to drive the shaft to create enough power, after much is lost, so that the end amo unt of power is greater than zero. Rated power is the maximum power output of a turbine, which is dependent on a number of factors, especially the generator.

    After this it should be easier for the domains to be turned because the more domains that are turned, the easier it is for others to be turned. After the initial few have taken time to be fully turned, they should begin to have an affect on the surrounding domains

    - The likely benefits of exposure to radiation must outweigh the risks involved. - The radiation does must be the minimum consistent with obtaining good quality images or destroying malignant cells. - It must not be possible to obtain equally useful information by less risky methods.

  2. Molecular stability (rheology) of a plastic carrier bag through stress - strain tests.

    To calculate stress the formula 'stress = load/area of cross section' is used. Strain is the deformation of a material in relation with stress, or the deflection of a material due to force. For this experiment I need to calculate these three.
