Homework Help: Help calulating bolt strength to prevent beam bending

  1. Apr 8, 2010 #1
    1. The problem statement, all variables and given/known data
    The attachment shows a side section of a water tank.(lined with Marine Ply)

    The section will be bolted to a fixed bottom section with 4 bolts.

    I'm trying to determine the size and strength of bolts required to do this.

    2. Relevant equations

    Hydrostatic force?
    UDL beam loading?

    3. The attempt at a solution

    My attempt at starting this problem is shown in the attachment.

    Ive calculated the the hydrostatic force on the section.
    The pressure on the section varies with depth from 9810pa to 0pa at the top.

    Is this a varying uniform load beam problem?
    Or is it a point load problem acting at the centroid of the triangle (2/3rds of the way down)

    Am I wrong here?

    Also where do I go from here to calculate the minimum strength of each of the four bolts to prevent the section from bending?
