Dr. Joe.

We are using 1 CIM w/ 12:1 ratio.

An ME here would like to know how you calculated the stress. Below is his observation from the photos as well as conversations with me.

"The initial interface is 2 lines of contact (essentially zero area) between the shaft and the D hole. It is only after material begins to deform (ever so slightly) that area contact is made. I am curious what he uses for stress area and how he determines it."
