hi i need to calculate the torsional stiffness of a sample, the data is in the excel file.(adsbygoogle = window.adsbygoogle || []).push({});

To work it out it = 1/samplek= 1/totalk - 1/machinek

the machine k was given as 42800NM/radian

the total k is the slope of the line which comes to y=658x

what i dont get is what am i meant to do with y=658x,

cheers any help would be great
