Homework Help: Determine the bending of a bar

  1. May 24, 2013 #1
    1. The problem statement, all variables and given/known data
    Hello, i have problem with the following:
    Determine the bending of the free end of an adjacent bar. The bar have flexural rigidity EI


    2. Relevant equations

    q = -dt/dx = -d^2M/dx^2 = d^2/dx^2(EI*d^2w/dx^2)

    3. The attempt at a solution

    x = 0; w = 0, d2/dx = 0
    x = l, T=0, M=M0

    I integrated 4 times and putted in those initialvalues but it didn't get my the correct answer.

    The answer should be w = PL^3/(3EI)

    Well, we can't say what went wrong without seeing your work. By the way, did you use your boundary conditions to determine the constants of integration when you did your calculations?
