A power generating company has asked to check if one of their steam turbines is safe enough to continue its operation. After investigation, the main shaft and the blades and found have degree of grain growth along with some voids formed within the grains and also at the grain boundaries. Do you think it is safe to continue the use of the turbine?  (5 Marks) What would be the likely failure mode if the shaft or blades fail?  (5 Marks) Explain the most likely failure mechanism for the potential failure mode? (8 Marks) What would be your suggestion to prevent this damage from happening again? (7 Marks)

Given the shaft described in Question 19, determine minimum principal stress.  Provide your answer in MPa, but do not include units in your submittal.

Given the beam shown in Question 1F, find the internal moment at node B.  Calculate your answer in kN m, but do not include units in the answer.  Include a sign in your answer.  If the moment is compression on top, the value is positive; if it is tension on top, the moment is negative .

Given the beam in Question 1, which choice best describes the moment reaction at the right end?

Given the simple span beam FBD, which choice best describes the direction of the internal moment at A?
