Plane Geometric Figures with Curved Boundaries

PLANE GEOMETRIC FIGURES WITH CURVED BOUNDARIES [Pg.6]

S = arc length subtended by 0 l = chord length subtended by 0 H = maximum rise of arc above chord, r — H = d [Pg.6]

A (circle) = Jtr2 = VinD2 A (sector) = VbrS = 1Ar29 [Pg.7]

Ring (area between two circles of radii r2 and r2) The circles need not be concentric, but one of the circles must enclose the other. [Pg.7]

Catenary (the curve formed by a cord of uniform weight suspended freely between two points A, B Fig. 3-8) [Pg.7]
