A cantilever is a beam supported on only one end. The beam transfers the load to the support where it has manage the moment of force and shear stress. Moment of force is the tendency of a force to twist or rotate an object.Shear stress is defined as a stress which is applied parallel to the face of a material.he formula for the maximum stress a cantilever beam can tolerate is given by. 1  Ï max = (M max) * (y) / (I), Where M max is the maximum moment (which is equal to M 1 + M 2), y is the distance from the center to the outer edge, and I is the area of the cross-section of the beam.
Epsilon is the fifth letter of the Greek alphabet, corresponding phonetically to a close-mid front unrounded vowel. In the system of Greek numerals it has a value of 5. It was derived from the Phoenician letter He . Letters that arose from Epsilon include the Roman E and Cyrillic Ðµ.
Even the ubiquitous [math]\pi[/math] has meanings other than that of the ratio of a circle's circumference to its diameter. http://en.wikipedia.org/wiki/The... Theta is just a Greek letter used often with angles and with polar coordinates as a substitute variable, not unlike the fabled x in algebra. Neither theta nor x have any special meaning except with a particular context.
