Data Master 2003
Free software for automation of professional test and measurement systems, data acquisition, processing and analysis. Especially suitable for scientists who would like to make high-performance, precise measurements in the experimental physics.
Sheet Lightning is a specialised engineering 2D/3D CAD System for creating and unfolding sheet metal designs for fabrication or manufacture. It handles cylinders, cones, square-to-round adapters, ovals, intersections and mutli-intersections.
BeamBoy is a free engineering utility for calculating stress and deflection of structural beams under load. May also be used for shafts. BeamBoy is menu-driven and intuitive.
The program is intended for simulation of kinematics and dynamics of planar and spatial mechanical systems. The following performances are available as results: coordinates, velocities, accelerations, reaction forces, forces in active elements etc.
This multi-language calculation package includes solutions for gearing, belt, chain, springs, beam, shaft, and many others. MITCalc support 2D and 3D CAD systems, Imperial and Metric units and many international standards (ANSI, ISO, DIN….).
