Calculate the moment and the sag

  1. Nov 11, 2016 #1
    The bridge is full extend 35 meters long, and retracted 17,5 meter long.
    When the bridge is installed it rest on piont(375kN) and a
    hydraulic pomp (525kN) , the mass of the bridge is 15 metric ton.

    my question is how do I calculate the bending moment diagrams when it is extending and how do i calculate the bending when it is at 35 meters.

    More information is needed before this problem can be analysed properly .

    Is this a homework question ?
