[x_eyeless_x]

Homework Statement

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.

Homework 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
