A six-cylinder engine uses pushrods to actuate the valves. The pushrods are 8.0 mm in diameter and are 650 mm long. Suppose the temperature can change from -40^oC to 116 ^oC. If the pushrods are allowed to expand unrestrained, calculate the change in length in mm to two decimal places. Assume they are made from AISI 1040 steel, E = 207 GPa, and have a coefficient of thermal expansion of 11.3 x 10^-6/^oC.

If the pushrods were installed with zero clearance between the parts when at 25^oC, Find the clearance in mm to three decimal points between the parts when the temperature is at -40^oC.

If the pushrods were installed with zero clearance between the parts when at 25^oC, Find the clearance between the parts when the temperature is at -40^oC.

Find the stress in MPa in the rod if the temperature rises to 116^oC.

In the process of producing engine valves, the valves are subjected to a first grind. Valves whose thicknesses are within the specification are ready for installation. Those valves whose thicknesses are above the specification are reground, while those whose thicknesses are below the specification are scrapped. Assume that after the first grind, 71% of the valves meet the specification, 18% are reground, and 11% are scrapped. Furthermore, assume that of those valves that are reground, 90% meet the specification, and...

Given: A short cylinder of steel has a diameter of 150 mm and length of 500 mm. It comes out of a heat treatment process at a uniform temperature of 200oC and is plunged into an unstirred bath of oil at a temperature of 20oC. Find: Considering heat loss from only the cylindrical surface (ignore the ends), which orientation would cool more quickly? One orientation is for the axis to be parallel to gravity and the other perpendicular to...
