WebThe circle-chord method is a construction that either redraws a graph to show that it is planar or shows that it is not planar. The construction is as follows: 1. First, nd a cycle … WebTheorem 10.7 Perpendicular Chord Bisector Theorem If a diameter of a circle is perpendicular to a chord, then the diameter bisects the chord and its arc. Proof Ex. 22, p. 550 Theorem 10.8 Perpendicular Chord Bisector Converse If one chord of a circle is a perpendicular bisector of another chord, then the fi rst chord is a diameter.

This method employs a tooth caliper that is referenced from the gear’s tip diameter. Thickness is measured at the reference circle. See Figure 5.1. Fig.5.1 Chordal tooth thickness method. (1) Spur Gears. Table 5.1 presents equations for each chordal tooth thickness measurement. WebThe following are the methods of setting out simple circular curves by linear methods and by the use of chain and tape: 1. By ordinates from the Long chord 2. By Successive Bisection of Arcs. 3.
