Hello! Glad i have found this forum!

I was looking at some bicycle frame tests. For headtube for example, the stiffness of the frame is reflected in N/degree. Then it divides to kg to find out the stiffness-to-weight ration.

For bottom bracket, they are measuring it in N/mm.

My question is: if i can measure the deflection of the frame in mm, how can i achieve the final result in N/degree? IS there a possibility to transform mm in N/degree? The frame is loaded with 20 kg to see how much it deflects.

Reformulated: if i know the deflection in mm, and the weight of 20 kg applied to deflect the frame, how can i find out the final result in N/degree?

Any help is really appreciated! Thank you very much!

F=ma
o=cos(omega)
