Reference Answer
### (a) Creep Test Procedure and Strain vs. Time Diagram
#### Concept of Creep
Creep is the time-dependent, permanent deformation of a material subjected to a constant load or stress at an elevated temperature. It is a critical consideration for components operating under high temperatures for extended periods, such as turbine blades, boiler tubes, and high-pressure steam pipes.
