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.
The (Sigma sign) is the 18th letter in the Greek alphabet. Mathematically, Sigma is a summation notation which basically means âsum it upâ. This math symbol was first used by Leonhard Euler, a Swiss mathematician, in representing the addition of a series of mathematical expressions. Golden Ratio Another popular math symbol is the Golden Ratio which is also called the divine proportion or golden section or golden mean.
