Engine Bearings - Main and Rod - Engine Builder Magazine

29/4/2016· Most rod and main bearings run best with .0007˝ to .001˝ of clearance for every inch of crankshaft journal diameter, or .0015˝ to .002˝ inches of oil clearance for a 2-inch diameter shaft – but these nuers will vary with the oil viscosity and appliion. Typically, an engine builder might add .0005 inches of additional clearance for a

NASA - The Right Sf for Super Spaceships

Composite materials, like those used in carbon-fiber tennis rackets and golf clubs, have already done much to help bring weight down in aerospace designs without compromising strength. But a new form of carbon called a "carbon nanotube" holds the promise of a dramatic improvement over composites: The best composites have 3 or 4 times the strength of steel by weight--for …

Thin vs. Thick shells - Technical Knowledge Base - Computers …

3/8/2016· The statement that thick shells tend to be stiffer than thin shells applies only to the bending components of shells, and to models in which meshing is too coarse. When meshing adequately captures bending deformation, thick-shell elements are more flexible because of the additional shear deformation that is not captured through thin-shell formulation.
