ENTC 207 Lab FinalTensile Testing Steps - correct answer 1. Place specimen in tester 2. Apply tensile load until sample breaks 3. During loading measure tensile load and length at intervals 4. Measure length after sample breaks 5. Calculations Stress - correct answer force / cross section area Y-axis psi Strain - correct answer (final length- original length) / original length X- axis in/in Modulus of elasticity - correct answer -Stress/strain (straight part of graph) -measure ...

stress - Answer force divided by area; calculate at each measurement interval strain - Answer (final length- original length)/original length Modulus of elasticity - Answer Stress/Strain in straight line portion of graph; can't calculate when graph is not straight (measure of stiffness) percent elongation - Answer final strain x 100% Proportional limit - Answer when the behavior is elastic but not proportional
