Beam Equations:
| δ | = | deflection in unit length |
| a | = | distance where load is applied from support |
| P | = | force |
| L | = | total length of beam in unit length |
| x | = | distance from support where P is applied in unit length |
| E | = | Young’s Modulus |
| I | = | Moment of Inertia |
| M | = | Moment |
| σ | = | Bending Stress |
| c | = | Distance from Neutral Axis to Extreme fibers |
| V | = | Sheer Stress |
