    hi guys was doing one of the questions sort of stuck as i dont know much about cantilever beams. ive got this question here:

    Consider a cantilever beam of length L carrying concentrated masses at both of its mid-lenght and at its tip. the cantilever may be assumed to have negligible mass:
    find the equation of cantilever deflection solely under a concentrated load applied at its tip as a function of a positive variable measured relative to the fixed end and also the flexibility matrix of a cantilever system equation abpve, matrix element 1,1 1,2 2,1 2,2

    thanks guys

    What's the relation between the second derivative of deflection and the moment?
