    Using Macaulay's method of deflection on a cantilever beam

    Ah I see what you're saying, that makes more sense. Thanks very much for your help, I really appreciate it.

    Using Macaulay's method of deflection on a cantilever beam

    Ah yes, I see where I have put the incorrect x value in, thanks! As for the negative slope, is this what you mean by having a negative slope when looking at the free end?

    Using Macaulay's method of deflection on a cantilever beam

    Hi, sorry I've drawn the beam out mirrored as I was trying to compare it to a similar one done in class. My diagram is shown with the fixed end on the right. There is 19.2kN reaction force at the fixed end, I am just not sure whether this is incorporated into the equation.

    Using Macaulay's method of deflection on a cantilever beam

    Homework Statement i) Determine the slope of the beam 1m from the wall. ii) Calculate the deflection at the free end of the beam. Homework Equations Macauly's method of deflection: M = -RX + W[X-a] Integrate once for slope Integrate twice for deflection The Attempt at a Solution [/B] It...

    Find the principal stresses in a shaft with torque applied

    I see what you're saying, I guess when I saw 'principal stresses' I thought about what we had learned in class and to draw mohrs circle. I am not sure how I would go about finding the maximum and minimum principal stresses without applying a bending stress? I have drawn the following loading...

    Find the principal stresses in a shaft with torque applied

    Homework Statement Homework Equations M = Fd σ/y = M/I T/J = τ/r σalternating (σa) = σmax - σmin / 2 σmean (σm) = σmax + σmin / 2 soderberg: σa/σ'e + σm/σy = 1/FoS The Attempt at a Solution I am still unsure whether my progress so far is correct but.. I have calculated J to be 38.35e-9 m4...
