The nuchal ligament in a horse supports the weight of the horse’s head. This ligament is much more elastic than a typical ligament, stretching from 15% to 45% longer than its resting length as a horse’s head moves up and down while it runs. This stretch of the ligament stores energy, making locomotion more efficient. Measurements on a segment of ligament show a linear stress-versusstrain relationship until the stress approaches 0.80. Smoothed data for the stretch are shown.
The segment of ligament tested has a resting length of 40 mm. How long is the ligament at a strain of 0.60?
A. 46 mm
B. 52 mm
C. 58 mm
D. 64 mm
