Cantilever beam bending moment and shear force

    1. The problem statement, all variables and given/known data
    im trying to write a program for a class but first i need the formulas for the bending moment and shear force. i have the displacement and angle of the cantilever beam under a point load:

    Y = -[(WX^2)/(6EI)][3a – x] for 0<x<a
    Y = -[(Wa^2)/(6EI)][3x – a] for a<x<L

    Theta = Wa^2/(2EI)

    2. Relevant equations
    y = displacement
    E = young's modulus
    I = moment of inertia
    L = length of beam
    w = uniform load (weight per unit length)

    3. The attempt at a solution

    please help, i have to write 3 programs due tomorow and cant get started without these formulas :(
