QUESTION OF THE WEEK

Question of the Week: 9/13/2006

We all know how to calculate the "thrust" following a Contracting Triangle, but how does one calculate the "thrust" following Expanding and Neutral Triangles.

Answer:

Sanjay Vidyalankar of New Delhi India asked this question back in mid August. I've expanded the question to cover all bases.

Contracting Triangles produce the most dramatic, post-pattern behavior with a "thrust" nearly equal to the widest leg, which in a contraction must be wave-a or b. NEoWave Neutral Triangles (where wave-c is the longest wave) exhibit post-pattern "thrusts" that are about 75% of the width of the largest wave (usually wave-c, but could be b or d). Expanding Triangles have the smallest post-pattern "thrusts," which are usually about 50% of the longest leg (usually wave-e, but could sometimes be wave-d in unusual situations).
