    Lect7 Distributed Loads on Beams Lect7 Distributed Loads on Beams Presentation Transcript

    • Mindanao State University Iligan Institute of Technology College of EngineeringDistributed aLoads on Beams Force Gevelyn Bontilao Itao, MOE
    • Distributed Loads Distributed loads: - consists of the weight of materials supported directly or indirectly by the beam, or it may caused by wind or hydrostatic pressure.gsbitao_2013
    • Distributed Loads It can be represented by plotting load w supported per unit length L. It is expressed as N/m or lb/ft.gsbitao_2013
    • Distributed Loads - The direction of the intensity of the load is indicated by arrows shown on the load intensity diagram. - This system of forces can be simplified to a single force W and its location x can be specified.gsbitao_2013
    • Distributed Loads Hence, the magnitude of W is equal to the total area A under the curve.gsbitao_2013
    • Distributed Loads Example 1: Determine the magnitude and location of the equivalent resultant force acting on the shaft.gsbitao_2013
    • Distributed Loads Example 2: A beam supports a distributed load as shown. Determine the equivalent concentrated load and its location, and the reactions at the supports.gsbitao_2013
    • Mindanao State University Iligan Institute of Technology College of EngineeringCentroid fora Force Composite Bodies Gevelyn Bontilao Itao, MOE
    • Centroid for Composite Bodies Center of Gravity: - a point which locate the coordinate of the center of gravity of a system of particle..gsbitao_2013
    • Centroid Centroid: - a point which defines the geometric center of the object. It is independent of the body’s weight and dependent on the bodies geometrygsbitao_2013
    • Centroid Centroid: - a point which defines the geometric center of the object. It is independent of the body’s weight and dependent on the bodies geometrygsbitao_2013
