Answer must be coorect -- when using three-wire connections to a strain gage to reduce the effects of leadwire resistance changes with temperature, a phenomenon called leadwire desensitization can occur. If the magnitude of the leadwire resistance exceeds 0.1% of the nominal gage resistance, significant error can result. Assuming a 18-gauge (AWG) platinum leadwire (resistivity 10.6×10-8 S2m) and a standard 120 22 gage, how long can the (individual) leads (in inches) be before there is leadwire desensitization?

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?
