- 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?You are given a sample of polypropylene and wish to find out the volume % crystallinity. You know that the density of 100% crystalline polypropylene (ρc) is 0.946 g/cm3, and the density of 100% amorphous polypropylene (ρa) is 0.855 g/cm3. Through your careful measurements, you determine the density of the sample (ρs) is 0.93 g/cm3. Use the following equation to determine the volume % crystallinity (ν) of your sample.

- A tentative rule was given about tipping in Testing Experiment Table 8.4, where if a vertical line passing through the object's center of mass is within the object's area of support the object does not tip. According to the rule, the full box of crackers in the following experiment, which has a width of 13 cm and a height of 20 cm, was seen to tip at an angle of: θc=tan−1(13 cm/20 cm)=33∘θ According to the rule, at what angle will a box with the left half filled with crackers begin to tip? Assume the box is light-weight and that the contents remain in the configuration inabaqus but I have only lame's constants to define potential function mu and lambda. I am confused with abaqus terminologies, it needs C10 and D1. After some search I found that lame constant lambda is shear modulus mu and C10 = mu/2 And lame constant mu = bulk modulus kappa, D1 = 2/kappa I am bit confused with these terminologies as haven't done such analysis before5.
