Procedure

1. Measure the thickness of the wire at several locations and calculate its mean value.
2. Set the required temperature of the wire system using the apparatus.
3. Measure the mass and dimensions of the load box.
4. Measure the extension of the wire at one-minute intervals and record the corresponding time and extension values.
5. Plot the Extension–Time graph. The resulting graph represents the creep behaviour of the material.

Virtual Procedure

1. Start the experiment by clicking the Play button.
2. Observe the extension of the specimen wire in the simulation window.
3. Record the extension values at regular time intervals.
4. Continue the simulation until the wire breaks and observe the final extension.
5. Observe the graph plotted between extension and time.
6. Use the Pause, Play, and Restart controls to view the values of different parameters at various stages of the simulation.

Note:

• For better visualization in the virtual simulation, the specimen is displayed as a thicker rod. In an actual creep test, the specimen is a thin wire (thread-like) of the test material. This visual representation does not affect the experimental principle or the observed creep behaviour.
• Various interactive graph features, such as zooming and panning, are available. Hover the mouse pointer over the icons above the graph to view the function of each feature.
