4 2 MOHR CIRCLES PROBLEM You've been working in the lab to determine the strength of an altered granitoid which hosts mineralization. The company you work for wants to start a deep underground mine in the region and it is imperative that the strength of the altered granitoid is well characterized. You conduct a series of experiments on the granitoid to develop a Coulomb failure criterion for the altered granitoid. All of your experiments were conducted in dry conditions (i.e., no pore fluid pressures). Plot up your 3 experiments as Mohr circles, fill in the table below, and determine the Coulomb failure criterion for the altered granitoid.
