    How Does Acceleration Impact Stress and Extension in a Steel Rope?

    Yes, I think :-) And your explanation is a hell of a lot simpler!

    How Does Acceleration Impact Stress and Extension in a Steel Rope?

    Hmmmm not sure! I may be on completely the wrong track here but these are my thoughts... if the object was accelerating at 10m/s2 then it would have no force against it so tension in the cable would be zero. However, if the object was stationary it would be working against the full gravitational...

    How Does Acceleration Impact Stress and Extension in a Steel Rope?

    I do apologise for being such a numpty it's been far too many years since I last attempted anything like this so you'll have to bear with me. Right, I presume what you're saying is mass x gravity - T = mass x acceleration In that case, 5000x10 - T = 5000x8.6 T...

    How Does Acceleration Impact Stress and Extension in a Steel Rope?

    Thank you for the advice what a complete idiot to miss out something so basic :-) So I need to use Force=mass x acceleration to determine the actual 'downward pull', for want of a better word, of the load. In that case if I have (5*10^4) * 1.4 the force would be 7 *10 ^4. Would the rest of my...

    How Does Acceleration Impact Stress and Extension in a Steel Rope?

    Homework Statement A winding engine lowers a load of 5 tonne at the rate of 1.4m/s2 for a distance of 10m. Assuming that the load is suspended from a steel rope 12mm in diameter calculate the stress and the extension in the rope after traveling this distance. Assume Esteel=200 GN/m2 and...
