Can one correlate the effects of a change in weight to the transmission of vibrations (fish strike) through a fishing rod? I'm not an engineer. I don't know what equations may apply. I'm not even certain I'm describing the question correctly. I'd appretiate any assistance. I've attempted to gather what I could through the Internet and understand that human physical sensitivity is measured as a matter of degree change that can be detected. The few articles I could find on fish strikes show measurements in grams force. I am guessing that this would equate to the rod in how much grams force is required to effect a physical movement of X degrees on the fisherman's grip. A change in the weight of the rod would then change the force required to affect the grip. I'm sure that there are many variables that would need to be considered; angle of the rod to the force being applied, distance from grip to tip top, etc.
