1. A shape memory wire is loaded and unloaded at room temperature of 23◦C to produce a residual strain of 0.04%. 
2. 
   
3. (a) Plot the recovery strain as a function of temperature as the material is heated to 44◦C. 
4. 
   
5. (b) Plot the recovery stress as the material is heated to 44◦C. 
6. 
   
7. (c) Combine the results of parts (a) and (b) to produce a plot of blocked stress and free strain 0.
