3. Now draw two lines which are tangent to the Mohr circles, one above and one below the 0. axis. These lines define the 'Coulomb failure envelope'. A Mohr circle that plots inside the envelope, without touching it, represents a state of stability with no failure; Mohr circles which plot on or beyond the envelope represent unstable stress states, which exceed the rock rupture strength and will result in failure by fracturing. Label these zones on your plot.

Using the failure envelopes you have constructed, predict whether the Berea sandstone would fail under the following conditions of Pc and 0... Also indicate what type of deformation you would expect to see in each core sample (Le. brilllc or ductile). Do this on a new 0.. vs. ‘t graph using the same scale and the failure envelopes traced from your first plot.

6. Based on the experimental data, what orientation would you expect naturally occurring brittle shear fractures and ductile shear zones to make with the principle compressive stress direction o₁? Draw some sketch diagrams to illustrate this.

A. We have found that the coordinates of the drainage grate are 40° 51.593' N, 74° 11.936' W, and the coordinates of the home plate are 40° 52.117' N, 74° 11.711' W. So, we have a right triangle with the points (40° 51.593' N, 74° 11.936¹ W; 40° 52.117' N, 74° 11.711' W; 40° 51.593' N, 74° 11.711' W). The length of the side A (40° 51.593' N, 74° 11.936' W; 40° 51.593' N, 74° 11.711' W) is 1040.80 ft. The length of the side B (40° 52.117' N, 74° 11.711' W; 40° 51.593¹ N, 74° 11.711' W) is 3180.02 ft. Hence, the straight-line distance is C = √1040.80² +3180.02² = 3346.01 ft.

We have found that coordinates of the letter "H" are 40Â°51.485'N, 74Â°12.080' W, and the coordinates of the manhole cover are 40Â°51.800'N,74Â°11.883'
