The EngineersToolbox (ETBX) is an intuitive software package that enables the engineer to interactively explore solutions to typical engineering systems and scenarios. The graphically driven system provides rapid solutions to engineering problems using first-principles, empirical correlations, experimental data, rules-of-thumb, and numerical solutions of conservation equations. It eliminates the need to shift through reference books, minimizes user-induced error while performing such calculations and delivers a fool-proof method of performing quick calculations. It is a comprehensive tool for engineering design, analysis, and reference. The software captures years of experience and expertise from various sources. The underlying methods are captured in an easy to use format; therefore ensuring repeatability and natural documentation of the calculation procedure.

ETBX can be used to obtain quick estimates of performance parameters for simple as well complex situations. It can be used to obtain directional impact of design changes on performance parameters and eliminate less fruitful concepts during a design process. The current version of ETBX covers a comprehensive range of engineering specialties, including solid mechanics, dynamics and controls, fatigue and fracture mechanics, fluid mechanics, heat transfer, numerical methods, and engineering reference utilities.
