A six-cylinder engine uses pushrods to actuate the valves. Thepushrods are 8.0 mm in diameter and are 650 mm long. Suppose thetemperature can change from -40oC to 116 oC.If the pushrods are allowed to expand unrestrained, calculate thechange in length in mm to two decimal places. Assume they are madefrom AISI 1040 steel, E = 207 GPa, and have a coefficient ofthermal expansion of 11.3 x 10-6/oC.
If the pushrods were installed with zero clearance between theparts when at 25oC, Find the clearance in mm to threedecimal points between the parts when the temperature is at-40oC.
If the pushrods were installed with zero clearance between theparts when at 25oC, Find the clearance between the partswhen the temperature is at -40oC.
Find the stress in MPa in the rod if the temperature rises to116oC.
