As an engineer you are asked to evaluate the feasibility of a device which operates in a temperature cycle (Option A: from initial stress-free conditions at 120C down to 50C ). The critical component of the device contains an aluminium plate clamped between two rigid endplates. At the start of an operating cycle the working temperature is 120C. The tensile strength of aluminium is 100MPa and the modulus is 70GPa. You are also presented with the option B) to recommend the lower temperature be raised to 70C. What do you recommend? Select one: a. Do not recommend A, recommend B b. Do not recommend A, do not recommend B c. Recommend A, recommend B as well d. Recommend A, do not recommend B
