Let us say that a fusiform muscle of length L and PCA is attached to bones by tendons of length 0.9L and cross-section area f(PCA) (f<<1) on either end. This total length of 2.8L is kept fixed as the muscle contracts by 20% and develops a force corresponding to 15N/cm2. Use the data in the provided table to answer the following.
(a) Find the strain in the tendons. How does it compare to the ultimate percent elongation (UPE) for tendons?
(b) Relate f to Y for the tendon.
(c) Using the value of Y from the table, compare the diameters of the muscle and tendons.
