Q3. How does increased loading change L, W, and t? When F doubles from 4.0 N to 8.0
N for the small rubber band, does the deformation, L-L0, also double? When F doubles from 4 N to 8 N for the large rubber band, does the deformation also double?
As the load increases, L increases and W and t decrease. From 4 N to 8 N, the deformation does not double; it doubles from 1N to 4N, and from 2N to 15N. The deformation rate slows as more force is applied. From 4N to 8N on the larger rubber band, the deformation does not double either. Both the small and large rubber bands deformed at approximately the same rate.

Q4. What is the reason for the “2” in the cross-sectional area computation in Tables 2 and 3?
Since values for width and thickness were only obtained for one side of the rubber band, they must be multiplied by 2 to account for the other side. However, the rubber band used in our experiment was cut, so we did not perform this calculation.
In this lab, rubber bands were used to represent tendons to show …show more content…
Construction of a load-deformation curve
Q1. If the model represents a tendon, what does each individual rubber band represent?
Each individual rubber band represents the fascia (endomysium, perimysium and epimysium), which combine to form the tendons.

Q2. Describe the behavior of the fibers as the applied load is increased from 0 N to 10 N

As the load increased from 0 N to 10 N, both rubber bands more than tripled in size from their original length. The rubber band with less slack initially showed a quicker decrease in the width of the band as the load was increased. It took longer in the rubber band that had more slack initially to become thinner because the shorter band experienced more tension in the earlier stages of increasing the load. When the 10 N load was applied, both the bands appeared to have similar tension and the width was also similar in size. Also, at the 10 N load, both bands had reached a similar length to each
