Materials for Mathematics Teachers

To the teachers who attended the workshop on 11/15:  I enjoyed that hour, hope you did too.  The data and slide show are here now.  Will be adding some to the slide show and data both over the next few weeks.  Definitely check back before the spring semester.

We're running the experiments with electrical solder and will post that data as soon as it's available.   It appears that regular electricians solder ($1.50 at Walmart) will do the job just fine.   Creep loads are in the range of 1.5 to 2.5 pounds.   The package even has the wire diameter on it so you don't need to measure.   We're working with 1.5 lbs and 2.5 lbs as our two load levels (approximately 3 MPa and 4MPa stress levels).  That will leave 2 lbs for students to predict based on the model (either from the power law formula or the linear plot of ln(strain  rate) vs. ln(stress))    Obviously will include the best values and the actual brand of solder in the final instruction sheet.  

UPDATE:  The final dataset required loads of 3kg and 4 kg.   The 3 kg test took about 25 minutes,  the 4 kg took about 7 min.   If you want to shorten the process a little you could use 3.5 and 4.  

If you will agree to run the experiment in your class and share the results (both mathematical and pedagogical) .  I'll be happy to provide you with the solder.  We can even loan you the weights if your science teacher won't.  If interested email me at rebobjr at panam dot edu.  Be sure to include your mailing (snail mail) address.
