MechPlane's Mechanical Decision Engines

Field notes

MechPlane organizes preliminary mechanical reasoning into five visible stages: Frame, Model, Screen, Compare, and Verify. Its declared coverage ranges from force, torque, shafts, gears, bearings, belts, chains, and springs to stress, deflection, fasteners, fits, tolerance stacks, machining, sheet metal, and manufacturing cost drivers. The homepage says each engine connects a result to assumptions, alternatives, and a verification step, although the supplied evidence does not show an individual engine or calculation interface.
