Intuitive meaning for Newton-meter

  1. Mar 11, 2010 #1

    I'm having a bit of trouble trying to grasp an "intuitive" meaning for newton-meter, kgf and newton when applied to motors and machines.

    For instance: If I have a 2Nm motor connected to a ball screw (supported on both ends), how much load can this motor move? How fast?

    Another problem: If I have a motor driving a linear shaft on an "up/down" movement (like the piston of an engine), how much force is made at the shaft's end? How much is needed to (for instance) break a sheet of glass, a brick or a 10mm thick MDF plate?

    Basically, I need some examples, directions or information about this kinds of scenarios, so I can build an "internal model" for how this units work...

    Sorry If I'm not so clear, I'm not a native english speaker.
