QF8: The 0.06R (mm)-diameter bar is made of a brittle material with the ultimate strengths of 0.1SR MPa in tension and 0.25R MPa in compression. The bar carries a bending moment and a torque, both of magnitude M. (a) Use the maximum normal stress theory to find the largest value of M that does not cause rupture. (b) Is the value of M found in Part (a) safe according to Mohr's theory of failure? 06R (mm
