low carbon steel having a tensile strength of 350 MPa and shear strength of 250 MPa...

low carbon steel having a tensile strength of 350 MPa and shear strength of 250 MPa is cut in a turning operation with a cutting speed of 200 m/min. The feed is 0.3 mm/rev and the depth of cut is 4.8 mm. The rake angle of the tool is 12 degrees in the direction of chip flow. The resulting chip ratio is 0.8. Using the orthogonal model as an approximation of turning determine... a.The shear plane angle. b. Shear force...

Aluminum oxide (Al2O3) has an elastic modulus of 400 GPa and a KIc of 4 MPa•m1/2 . A specimen is tested in tension and is found to deform elastically up to the point of fracture at a stress of 450 MPa. (a) Make a diagram of engineering stress-engineering strain to show this behavior. (b) Find the strain at fracture. (b) Estimate the flaw size (a) that caused failure (assume Y = 1). (c) If another specimen of the same size...

An ASTM A36 steel having a yield strength of 235 MPa, a tensile strength of 640 MPa, and an endurance limit of 210 MPa is subjected to a cyclic loading. Using the Goodman diagram, predict whether the material has an infinite fatigue life, or whether it will fail by yielding or fatigue, when the cyclic stress is between: (i) 0 and 250 MPa. (ii) 95 ± 220 MPa
