  • Magnetic Field B
    1,682 words
    Diamagnetics was discovered by Michael Faraday in 1846, but no one at the time thought that it could lead to any appreciable effects. William Thomson (Lord Kelvin), referring to levitation as the problem of "Moham ets coffin", had this to say: "It will ob ably be impossible ever to observe this phenomenon, on account of the difficulty of getting a magnet strong enough, and a diamagnetic substance sufficiently light, as the [magnetic] forces are excessively feeble". Fields strong enough to lift d...

  • Relation Between The Stress And The Strain
    1,537 words
    Simple Stress and Strain The strength of materials are expressed from the point of view of machine designer. A machine designer needs to know the properties of different materials so that he can select the most suitable material for each part of a machine. A machine designer uses his information of stress to make sure that the stress is reasonable and that each part of the machine is sufficiently strong. Strength of materials is the scientific area of applied mechanics for the study of the stren...
  • Characteristic Of Every Material Under Various Forces
    561 words
    Different shapes resist forces in different ways, so as every material withstands forces differently. To design a good and safe bridge, an engineer must know the forces in every member of the bridge. In turn, he must choose the appropriate material for that member, or for all members. He must know the characteristic of every material under various forces which may occur on the bridge. For example, should he choose concrete or stone for the pier and abutment? Is it steel instead of concrete which...
  • Appropriate Materials
    301 words
    When designing you will need to choose appropriate materials to make your design from. There are many different types of materials but some are more suitable than others for a variety of reasons. Here is a selection of those reasons. STRONG - The material will resist - Tension forces -Compression forces -Torsion forces -Shear Forces TOUGH - The material can withstand shock (e.g. Hammer Blows) BRITTLE - The material will break easily if subject to slight shock or force HARD - The material is long...
  • Ss The Direction Of The Friction Force
    976 words
    1 Access to Engineering Coulomb Friction Date: 2003-03-06 Objective: of the experiment is to verify the Laws of Coulomb friction through practical investigations, to obtain a set of results from different range of materials from which we would be able to understand FRICTION. Materials: wooden flat runaway, specimen blocks, various masses, hangers and pulley. Diagram of set-up N F The force that occurs when things slide against each other, that stops movement -- -its scientific name is friction. ...
