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 120 °C down to 50 °C). 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 120 °C. The tensile strength of aluminium is ~100 MPa and the modulus is 70 GPa. You are also presented with the option B) to recommend the lower temperature be raised to 70 °C. What do you recommend? Select one: O a. Do not recommend A, do not recommend B O b. Recommend A, do not recommend B O c. Recommend A, recommend B as well O d. Do not recommend A, recommend B

Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Part 1 At a temperature of 60°F, a 0.05-in. gap exists between the ends of the two bars shown. Bar (1) is an aluminum alloy [E = 10,000 ksi; v = 0.32; a = 12.5 x 106/°F] bar with a width of 2.7 in. and a thickness of 0.65 in. Bar (2) is a stainless steel [E = 28,000 ksi; v = 0.12; a = 9.6 x 106/°F] bar with a width of 1.6 in. and a thickness of 0.65 in. The supports at A and C are rigid.
