Hi everyone I have a quick question in regards to an experimental report I'm writing for my year 11 Physics class. Basically we have to test different variables that could effect a bungee cord fiber in relation to stress and strain by increasing the weight force on the fiber until it snaps. For the first part of the experiment I tested the effects of increasing the number of fibers.
The problem I face is that when I measured the diameters of the different grouped fibers using a digital caliper the single fiber was 0.13mm, three fibers was 0.26mm and five fibers was 0.25mm. I just want to know if anyone know why this might be the case, as it also happened when I was making different composite fibers. The method I used for making groups of fibers more than one was by clamping one end and spinning them.
Personally I think the fibers may be pressing into each other and causing the diameter to be smaller than expected. I just need someone to confirm this and explain further; or shows me what's really happening.
Thanks in advance,
Max
