Here is tour specimen in the Instron machine.  We have set up a program that will apply 300 pounds of force on the foot for 10,00 cycles.  
You can see that the displacement of the foot is about 1.15 inches. So with 300-340 pounds of force the foot is compressed about 1.15 inches.
This is the data of the force for each cycle. You can see that the average force is about 320 pounds.
This is the control center.  It has all of our graphs and our data outputs so we know what is happening and where we are at in the overall process.
The program  is running and you can see that everything is going as planned.
We had a bolt in this foot, but I took it out so I could put the bolt in another foot and start the testing.  This foot only made it about 5,000 cycles.  Something isn't working out the way we want it to and so we are going to go back to the drawing board.
