    critical buckling stress for cylinder

    Desertfox, When you say an effective length of 2, do you mean 2 times the cylinder stroke distance? Or 2 times the length of the rod?

    rod buckling calculation

    There is no support b/t pins. Well, that should definitely answer my question. Thanks for your help israelkk!

    rod buckling calculation

    So then what should my "l" be? You were saying earlier that it is from the piston to the rod bearing surface. But shouldn't it be taken from pin to pin when the cylinder is fully extended?

    rod buckling calculation

    Since the cylinder is supported at the two extremes (rod end and rear end), I don't understand why the effective length wouldn't be the distance from pineye to pineye when the rod is fully extended. Wouldn't the worst case be when the rod is fully extended out of the cylinder? That seems to be...

    critical buckling stress for cylinder

    Can anyone give me the calculations (or send me to a site) necessary to compute the critical buckling stress for the piston rod of a hydraulic cylinder. I know I'll probably use Euler's formula, but I don't know what to substitute for the "effective length" and "k" values. I've looked in...

    rod buckling calculation

    I have the 24th ed. It shows the formula P=(pi^2*I*E)/l^2. I just don't know what to use for the effective length "l". The cylinder is mounted by two pins (one at end of rod, the other at rear of cyl.) and the open center-center is 202". Anyway, I appreciate your help israelkk

    rod buckling calculation

    I've been looking in Machinery's Handbook and it gives me the calculations for a structural column (i.e. Euler's formula), but I don't know how to relate that to a cylinder. For example, what to substitute for your "k" and "l" values. The google search turned up nothing. Calman
