A steel piston ring has a mean diameter of 69.7 mm, a radial height = 4.2 mm, and a thickness b = 3 mm. The ring is assembled using
an expansion tool that separates the split ends a distance ō by applying a force Fas shown. The Inner radius, r,, Is 32.75 mm and the
outer radius, ro. Is 36.95 mm. Use Castigliano's theorem and determine the force Fneeded to expand the split ends a distance σ = 1
mm.
F
The force needed to expand the spilt ends a distance of 1 mm is
N.
