The weight of a big fish caught by a fisherman applies a force of 15 n to the nylon fishing line, which is 16 m long and has a diameter of 0.7 mm. a. estimate the normal stress in the fishing line. b. if the line stretches by 0.26 m due to the application of the force, calculate the normal strain in the line. c. calculate the true strain in the line and comment on the difference between normal strain and true strain. d. assuming that the nylon fishing line behaves in a linear elastic manner, estimate its elastic modulus from the given loading.
