Homework 6 Geology 3063 November 1, 2000 1. Draw a 2 dimensional Mohr Circle representation for the following stress conditions. 01=7 GPa 02=1 GPa Determine on and os for planes oriented at20°,40°and60°too1 2. Assuming joint system with strike and dip of NO,75°w, determine on and os on the joint surface if o1 is horizontal and has a magnitude of 12GPa and o2 is vertical and has a magnitude of 2GPa. What would on and os be if the joint surfaces were dipping to the East rather than to the West? 3. Use the Mohr Circle to "show" that maximum shear stress occurs on planes oriented at±45° relative to o11in2 -dimensional- systems. Last Modified November 1, 2000 Fall 2000
