Euler–Bernoulli beam theory (also known as engineer’s beam theory or classical beam theory) is a simplification of the linear theory of elasticity which provides a means of calculating the load-carrying and deflection characteristics of beams. A cantilever is a beam anchored at only one end. The beam carries the load to the support where it is forced against by a moment and shear stress. Maximum displacement of a cantilever Euler beam with a point load at its free end is related to the load on end of the beam, the beam length and the Area Moment of Inertia for beam cross-section.
| w | Maximum displacement of beam (mm) |
| P | Load on end of the beam (N) |
| L | Beam length (mm) |
| E | Young's Modulus for beam material (N/mm2) |
| A | section area (mm2) |
