Homework 6 Geology 3063 November 1. 2000 1. Draw a 2 dimensional Mohr Circle representation for the following stress conditions 7 GP g=1 GPa Determine on and os for planes oriented at20°,40°and60°toa1 2. Assuming a joint system with a strike and dip of noe, 75 w, determine on and os on the joint surface if o1 is horizontal and has a magnitude of 12G Pa and 2 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 o1 in2- dimensional systems Last Modified November 1, 2000 Fall 2000
