Show the locations of stresses on an appropriate sketch. 3. (a) If you were designing a metallic tool to be used at very low temperatures (negative temperatures), which material class would be the best option? (b) If you wanted to increase the strength of that tool for that very low temperature, which strengthening method would be the best option? Briefly explain your answer.arrow_forwardm.

- Find the dynamic viscosityarrow_forwardDetermine induced stressarrow_forwardThe thermal stresses in structural members are an important but generally ignored part of the overall structural analysis procedure. At times, these are of the order of load induced stresses as well which makes them worth the attention. Write a short note on the importance of recognising and evaluating thermal stresses in structures and also compare them with load induced stresses.arrow_forward
