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.
The most common current wing design is the cantilever. A single large beam, called the main spar, runs through the wing, typically nearer the leading edge at about 25 percent of the total chord. In flight, the wings generate lift, and the wing spars are designed to carry this load through the fuselage to the other wing.he second is the formula relating the cantilever spring constant to the cantilever dimensions and material constants: where is force and is the cantilever width. The spring constant is related to the cantilever resonance frequency by the usual harmonic oscillator formula.
