Wire ties were pulled until fracture. Table and force-extension curves show how test speed affects peak load and maximum elongation. As the speed was doubled from 2 to 4 inches per minute, the maximum elongation was reduced by almost half. As the speed was increased from 2 to 16 inches per minute, the maximum force increased by 7.5%.
