That's an idea...I could give that a try but I don't know how accurate it'd be. I thought about that. But the stress->strain requires Youngs Modulus does it not? I don't think it'd be possible to find the modulus for the strings I'll be using. :S

The problem is the string elongates during rotation and we need to know by how much.

I'm measuring from the axis of rotation (axis goes vertically through point "o"). Rotation is assumed to be steady; it is done by the motor taken from power drill and fed by a lab DC power supply which is kept at a constant amperage and voltage. I have access to me equipment that is...

Please ignore the periods in the diagram as it won't allow me to properly draw it otherwise. I have an object, attached to a string, rotating uniformly in a circle but at an angle to the horizontal plane. It is going at 80RPM (so relatively slow). How would one go about measuring the length...
