    Abstract : Popular Abstract in Swedish Hos järnvägsfordon ger den låga friktionen mellan hjul och räls upphov till långa bromssträckor, i allmänhet längre än lokförarens siktsträcka. Om föraren påbörjar en inbromsning först när han ser ett hinder på spåret kan det vara för sent. READ MORE

  5. 5. Wear behavior of wet clutches

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Niklas Lingesten; Luleå tekniska universitet.; [2012]

    Abstract : Human civilization is largely based on the transformation of stored chemical energy in the form of fossil fuels into usable work through the use of the combustion engine. In recent years, the awareness of problems such as global warming due to emissions of greenhouse gases and the depletion of fossil fuel reserves has increased. READ MORE
