By increasing stress, this rod (from 1a) eventually fractured. Estimate the maximum stress at crack tip. It is known that fracture occurs by propagation of an elliptically shaped surface crack of length 0.3 mm. This crack has a tip radius of curvature of 0.003 mm. Assuming that the applied stress is the result of the load of 47,124 N. Answer in terms of GPa (do not include units in answer)
