A strain gage is placed on the outside of the bar to measure normal strains in the longitudinal direction. 1.1 If the measured strain is ε = 550 x 10-6, what is the shortening δ of the bar? 1.2 If the compressive stress in the bar is intended to be 40 MPa, what should be the load P? 2.

Request: Can you please help me with answering the following question? Thank you. Question: A specimen of a ceramic material having an elastic modulus of 250 GPa (36.3 x 106 psi) is pulled in tension with a stress of 750 MPa (109,000 psi). Will the specimen fail if its “most severe flaw” is an internal crack that has a length of 0.20 mm (7.87 x 10-3 in.) and a tip radius of curvature of 0.001 mm (3.94 x 10-5 in.)? Why or why not?
