- The assembly consists of a brass shell (1) fully bonded to a ceramic core (2). The brass shell [E = 86 GPa, α= 18 × 10−6/°C] has an outside diameter of 33 mm and an inside diameter of 27 mm. The ceramic core [E = 320 GPa, α= 2.5 × 10−6/°C] has a diameter of 27 mm. At a temperature of 15°C, the assembly is unstressed. Assume L = 320 mm. Determine the largest temperature increase Δt that is acceptable for the assembly if the normal stress in the longitudinal direction of the brass shell must not exceed 65 MPa.arrow_forwardWhen a bar is cooled to -5°C, it will develop O(A) No stress OCB) Shear stress OC) Tensile stress O(D) Compressive stressarrow_forwardUsing the isothermal transformation diagram for a 0.45 wt% C steel alloy (Figure 10.40), determine the final microstructure (in terms of just the microconstituents present) AND approximate percentages of the microconstituents that form in a small specimen that has been subjected to the following time-temperature treatments. In each case assume that the specimen begins at 845°C (1550°F), and that it has been held at this temperature long enough to have achieved a complete and homogeneous austenitic structure. (a) Rapidly cool to 250°C (480°F), hold for 10^3 s, then quench to room temperature. (b) Rapidly cool to 700°C (1290°F), hold for 30 s, then quench to room temperature. (c) Rapidly cool to 700°C (1290°F), hold at this temperature for 10^5 s, then quench to room temperature. (d) Rapidly cool to 400°C (750°F), hold for 500 s, then quench to room temperature.arrow_forward

Decreasing the difference between the maximum and minimum stress values, as this effects the stress concentration factor b. Decreasing the temperature below the brittle-ductile transition temperature, to make it harder C. Polishing to reduce surface defects Od. Increasing its volume, to give a larger cross sectional area Oe. Increasing the grain size so there are less grain boundaries to initiate failurearrow_forward
