Aspacer made of sae 1020 hot-rolled steel is in the form of a hollow cylinder with a nominal inside diameter of 3.2500 in and an outside diameter of 4.000 in. it is to be mounted on a solid steel shaft with a heavy force fit. specify the dimensions for the shaft and sleeve, and compute the stresses in the sleeve and shaft after installation at maximum interference. also determine the deformation of the sleeve and shaft. use the basic hole system. the modulus of elasticity of steel, e = 30 × 106 psi and poisson’s ratio, = 0.29.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
