“Engineering Weight Calculator” is a simple application developed to simplify the task of theoretical calculation of mass and cost of standard engineering/structural components such as: - Plates/Chequered plates, - Round and polygonal bars, - Hollow round and rectangular pipes, - Standard rolled beams, channels, angles, tee sections, (Inbuilt dimensional data as per applicable ANSI/AS/BS/IS/ISO Standards included), - Non-standard/Generic beams, channels, angles, tee sections, etc. Other features: - Calculate mass and cost of multiple components added in a list. This list can be exported in the form of a Excel or text file for future reference. These files can be accessed in the default app folder when the device is connected to a computer via USB. - Calculate surface area of few of above mentioned components. - Includes Metric and Imperial units - Unit conversion for mass and linear dimensions units - Specific gravity for commonly used materials - Gauge conversion for thickness, Inch fractions conversion table - Tables for selecting some standard available round and rectangular hollow tubes. - Expression calculator to evaluate simple mathematical and trigonometrical expressions. Suggestions and comments for further improvement to enhance the application usefulness shall be highly appreciated and incorporated whatever feasible.
