A 3.00 inch diameter workpiece that is 25 in long is to be turned down to n2.384 inches. Process Specifications: a) Cutting Speed (V) = 300 ft/min, b) Feed (f) = 0.015 in/rev c) Depth of cut (d) = 0.044 in The bar will be held in a chuck and supported on the opposite end in a live center. With this work-holding setup, one end (15 inches) must be turned to diameter; then the bar must be reversed to turn...

A 3-inch diameter ground shaft rotates at 1000 rev/min in a lathe turned full journal bearing, which is 3 in long. SAE Grade 20 lubricant is used and the lubricant sump has a steady-state temperature of 100°F. The maximum lubricant temperature must not exceed 200°F. Analyze the assembly assuming average clearance and a H8/f8 clearance fit. Determine the following: a. The maximum radial load that the journal can carry and still operate under thick-film lubrication conditions. (6 points) b. The...

A long steel bar (20 mm diameter) at 455°C is placed horizontally in a water bath at 100°C under atmospheric pressure. (a) Estimate the initial heat transfer rate per unit length of the bar to the water when it is initially placed in water. You may assume emissivity of the steel bar to be 1. (b) What type of heat transfer mechanism is present when the bar has cooled to 110°C.
