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

Failure analysis testing is a mechanisms to understand how mechanical stress develops under the complex loading of vehicle dynamics to identify the cause of mechanical failure. It is known that mechanical failures due to metal fatigue of a certain type of jet engines follow a Poisson process. On the average based on the past records, a jet engine will have a failure once every 5000 flight hours. a. If such engines are scheduled for inspection and maintenance after every 2500...
