¶ Barrel
Index Entry
When we press against a barrel, the stress is satisfied by the tension hoop. Each hoop represents the circle of a single plane. Thus it is seen that simple curvature stresses act in a single plane, ultimately articulating that stress in diametric opposition of a line within the plane. The stresses are then ultimately focused to the infinite poles of parallels, because the latter are unaided in interstabilization.
