Slide 5

The first data reduction step is to determine the torsional stiffness of the sample. There are a number of approaches to doing this, but what we suggest is to plot the initial part of the torque-twist data, then fit a straight line to the linear part of the curve. Remember to convert your twist from degrees into radians. The slope of this fit gives you the overall stiffness.
