    Calculating Torque of a round spinning object
    Hi all. What a great site! :)

    Ok, My question relates to calculating torque on a machine.

    NOTE: I have looked at other questions asked before, but cannot find a formula that relates to my specific question and product dimensions.

    My machine has a round product that weighs 75kg and has an outer circumference of 900mm with the weight evenly distrubuted. It is mounted to a 40mm shaft, that spins freely through the use of some bearings.

    I need to work out how much torque is generated when the product turns, (In only one direction) so that I can match a brake unit to it, to stop it turning, bearing in mind the product is not turned by a motor and does not turn very fast. It just needs to stop turning when required.

    I hope I have supplied enough information for the question..

    Thanks in Advance

    MM

    Forgot to mention, force is applied to the outer edges of the product to make it rotate, not from the centre/shaft.
