- 1.3 A furnace wall is to be constructed of brick having standard dimensions of Two kinds of material are available. One has a maximum usable temperature of 1040°C and a thermal conductivity of 1.7 W/(m K), and the other has a maximum temperature limit of 870°C and a thermal conductivity of 0.85 W/(m K). The bricks have the same cost and are laid in any manner, but we wish to design the most economical wall for a furnace with a temperature of 1040°C on the hot side and 200°C on the cold side. If the maximum amount of heat transfer permissible is 950 , determine the most economical arrangement using the available bricks.A steel band 6mm thick is to be pulled on to a cylinder 30cm in diameter. The internal diameter of the hoop formed by the band is 29.98cm. By how much will it be necessary to increase the temperature of the hoop, so that it would slide over the surface of the cylinder? What stress will occur in the hoop when it reaches the same temperature as the cylinder, if the deformation of the cylinder may be neglected?A disk of SBR elastomer 3.0 cm in diameter 0.5 cmthick is used as a cushioning surface between two steel rods ofthe same diameter, as shown below (not to scale). a. If the rods are brought together with an axial force of 100 N such that the SBR is compressed elastically between them, what is the thickness of the SBR under load? b. Under the same conditions as part (a), what is the greatest possible diameter of the SBR under load? c. If the SBR is bonded to the rods, how far can one rod be rotated with respect to the other before the SBR/rod interface fractures? Assume that the rods are essentially rigid and the distance between them remains constant. Please answer in degrees of rotation.

The length of the cylinders and sleeves are equal. For the steel cylinder, A= 8000 mm2, E= 200 GPa, and α= 11.7 μm/(m°C). For the bronze sleeve, A= 16 x 103 mm2, E= 83 GPa, and α= 19.0 μm/(m°C). Compute the temperature change that will cause a zero load in the steel.A circular cross-sectional rod made of AISI Type 303 Stainless Steel is normally operated at126oF.

- Kindly show a step-by-step solution. Thank you A 6m rod with a 4mm gap between one of its ends and the surface of the wall next to it is secured solidly between two walls at 25°C. Calculate the highest temperature that the rod can withstand in degrees celsius while taking into account the maximum limiting stress of 67 MPa, where a = 19.5 m/mC°, and E = 130 GPa.14. A commonly used method of fastening one part to another part iscalled “shrink fi tting.” A steel rod has a diameter of 2.0026 cm, and afl at plate contains a hole whose diameter is 2.0000 cm. The rod is cooledso that it just fi ts into the hole. When the rod warms up, the enormousthermal stress exerted by the plate holds the rod securely to the plate. Byhow many Celsius degrees should the rod be cooled?Q4. Two long rods of the same diameter, one of brass(k= 85 W/mK) and the other of copper (k=375 W/mK) have one of their ends inserted in a furnace and the other ends exposed to the same atmosphere. At a distance of 105mm away from the furnace, the temperature of the brass rod is 120' C. Find the distance from the furnace in which the copper rod have the same temperature.
