    to slow the train over a long distance, to ensure that the speed is under the control. In stop braking condition, thermal fatigue cracks will initiate and propagate while under the drag braking condition, an extreme thermal input occurs which can fracture the wheel. When the brakes are applied for long periods of time, it will cause the heating of the thread and rim of the wheel, generated by frictional forces. Observation of the railway wheel has been made based on the wheels in Keretapi Tanah Melayu

    most complex stage of fatigue fracture. There is an irreversible change in the metal caused by repetitive shear stresses which is the most significant factor in the initiation process. The initiation site of any fatigue fracture is very small. It is never more than two to five grains around the origin. At the location of stress concentration points, the number would depend on geometry, environment, stress, and strength conditions. If this stage can be seized than fracture phenomenon would not take place

    Group 2: The significance of modulus of elasticity and fracture toughness for resin composites Kelly Griffith, Lance Gunter, Joshua Haentges, Erik Hageman, Zohra Hasham, Nellab Hashimi Modulus of elasticity is defined as the comparative stiffness of a material. A stiffer material will have a higher elastic modulus. Fracture toughness is the amount of stress required to propagate a preexisting flaw. It describes resistance of a material with a pre-existing flaw to fail. These two properties will

  • Essay On Car Body Manufacturing

    1276 Words  | 3 Pages

    i. Car Body Car bodies are usually made of steel or aluminium. They both have different properties and prices ranges that make it ideal. Aluminium has a lower density meaning the car will be lighter than if it was made from steel. It also doesn’t corrode easily so a car made of aluminium will last longer than that made from steel as the steel contains iron which will corrode. In saying this aluminium is much more expensive, and although it has better properties is may take the price of the car up

    Leonhard Euler, (born April 15, 1707, died Sept. 18, 1783), was the most prolific mathematician in history. His 866 books and articles represent about one third of the entire body of research on mathematics, theoretical physics, and engineering mechanics published between 1726 and 1800. In pure mathematics, he integrated Leibniz's differential calculus and Newton's method of fluxions into mathematical analysis; refined the notion of a function; made common many mathematical notations, including e
