Workshop crane calculation help needed

  1. Mar 20, 2013 #1
    1. The problem statement, all variables and given/known data
    need to calculate cantilever beam analysis, column analysis, pivot pin analysis, ram pins analysis
    the attached pdf has the picture of the crane i intend to use.



    2. Relevant equations
    Tensile stress, σ = F/A

    General bending equation: M/I = σ/y

    Moment of inertia for a rectangular section: bh^3/12

    Moment of inertia for a circular section: Ix = Iy = ∏D^4/64

    Moment of inertia for a hollow circular section: Ix = Iy = ∏(D^4-d^4)/64

    Shear stress on a bolt in double shear, σ = F/(∏/2)D^2

    Torque = Fr


    3. The attempt at a solution
    the pics attached shows the attmept of my calculation.
