A stress is suddenly applied to a muscle and then held constant while strain and strain‐rate are measured (see right figure). The phenomenon explaining the measured strain is called __________________. As the stress is maintained and the strain reaches steady state __________________ stresses dominate the total stress. a. Stress‐relaxation, elastic b. Stress‐relaxation, viscous c. Creep, viscous d. Creep, elastic
