Structural engineering models and applications
Draw free-body diagrams before selecting design equations
Maximum moment for a simple uniform-load beam is wL²/8
Distinguish serviceability, allowable-stress and factored-resistance frameworks using the actual specified combination.
Effective length factor K controls column buckling capacity
Load path continuity governs lateral-force questions
Geotechnical engineering models and applications
Effective stress equals total stress minus pore pressure
Use buoyant unit weight below the water table
Drained versus undrained strength depends on loading rate and permeability
USCS classification depends on grain size and plasticity
Active, at-rest, and passive earth pressures are distinct conditions
Construction engineering models and applications
Total float preserves the stated project finish; free float preserves successor early starts.
Bank, loose, and compacted volumes use swell and shrinkage separately
Critical path can shift after logic or duration changes
Crane capacity must be checked at the actual operating radius
Unit-price contracts pay by measured quantity; lump-sum pays for the scope
