4. a. Under what conditions would the tensile strength of rock be significant? (Consider bending condi tions for a rock mass.) b. A sample of clastic limestone yielded a compres sive strength of 41.4 MPa (6000 psi) and a shear strength of 7.6 MPa (1100 psi). What tensile strength value would you select for this rock if test ing was not possible? Explain how you would arrive at this value.
