Calculation (20) 1) Without drawing any of the hexagonal planes given below, determine which of the planes is, in fact, not a plane. (a)(1210), (b) (1210), (c) (1012) and (d) (1110). (5) 2) A cubic plane has the following axial intercepts: a-2/3, b=-2/3, e- 1/2. What are the Miller indices of this plane? (5) 3) A fatigue test is made with a maximum stress of 178 MPa and a minimum stress of -29.6 MPa. Calculate (a) the stress range, (b) the stress amplitude, (c) the mean stress, and (d) the stress ratio. (10) Discussion (40) 1) Tell me what do the black dots represent?? Why we need this structure? And how to realize this? (20) 400m 2) Discuss all differences that you observe between the following figures. Which one will be more dangerous and tell me why? What can we do to avoid it?
