Week 5:


     This week, in lab a design has been created for a table top tensile strength tester.  It was made using the Lego NXT as planned.  We did run into an issue with the load cell though.  We found a way to attach it to our design, but we do not have a way to get a reading from it.  The wires are in okay condition, but we have no clue where to plug them in.  The plan is to find a way to get a reading from the load cell next week.
     As far as the electrospinning goes, two of our group members have taken their safety tests and are ready to spin, so at the end of week 5 they are planning on going into the materials science lab and mixing the polyethylene and its mixtures to be spun the next day.
     Below is a picture of our tensile strength tester design created in Lego Digital Designer:
