An elastic string is fixed at one end and is wound on a drum of diameter 0.2m so that the tension in the string increases as the angle through which the drum turns increases. The torque Ton the drum then varies according to the law: T = Sr20 where S = stiffness of elastic string (S=120KN/m) r = radius of drum As the drum starts at 0 = 0, the work done can be calculated using calculus, for any given value of 0, as shown: ST de Determine the work done by the drum if it rotates through an angle of 0 = 2/3,

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 volume of the ligament stays the same as it stretches, so the cross-section area decreases as the length increases. Given this, how would a force F versus change in length ΔL curve appear?
