Q1 - PLANE STRESS: Consider a Mohr's circle, which is constructed from a plane stress state for which the centre is at C(80,0) and the stresses on the positive x-face are represented by point A(53, -45). Use this important information for the Mohr's circle to: Note: All stress values are in MPa. a) Determine stress components Ty1 and Tz1y1 in MPa for an element rotated in the counterclockwise direction by 28°. i) Iz1= Round your answer to 3 decimal places. MPa ii) Round your answer to 3 decimal places. MPa iii) Tz1y1² Round your answer to 3 decimal places. MPa Submit part 6 marks Unanswered b) Determine the principal stresses 01 and 02 in MPa as well as the orientation Op1 in degrees (9) measured in the counterclockwise direction. i) 01= Round your answer to 3 decimal places. MPa ii) 02 = Round your answer to 3 decimal places. MPa iii) Op1 = Round your answer to 3 decimal places. o Submit part 6 marks Unanswered c) Determine the average normal stress Taugand maximum in-plane shear stress Tmax in MPa as well as 081 in degrees (9) measured in a counterclockwise direction. i) Tavg= Round your answer to 3 decimal places. MPa ii) Tmaz= Round your answer to 3 decimal places. MPa iii) 081 = Round your answer to 3 decimal places. o
