A chrome steel shaft (k = 61 W/m-K) rotates inside of a bushing. The shaft diameter is 12 mm. During high-speed rotation, the friction causes the shaft temperature at the bushing to reach 175Â°C. The shaft is in a warm room where the ambient temperature is 35Â°C, the convective coefficient between the shaft and air is 5 W/m^2-K. A pulley is located on the shaft at the midpoint between the bushings. For extended life of operation, it has been determined that the shaft temperature at the midpoint should not exceed 100Â°C. What minimum distance (2L) must exist between the bushings to satisfy this condition (assume insulated tip solution)? Ans: 53.6 cm.
