🌉 Bridge-Laying Vehicle Lab: Scissor Launch Kinematics, Hydraulics and Tipping Stability

Launch a folded scissor bridge from a generic disaster-relief carrier and watch the machine, not the span: law-of-cosines and four-bar cylinder kinematics, cylinder force and pressure by virtual work, pump flow and energy, tipping safety factor with outriggers, soft ground and wind, then the laid bridge as a loaded beam. Unlike the truss member-force lab, the focus is the launching mechanism and the vehicle's stability. Educational engineering of a civil crossing vehicle with Blender-built assets.
