🌻 Oilseed Screw Press: Crank Torque, Cake Pressure and Thread Friction (2D section)

Cross-section of a hand-cranked oilseed screw press. Set the crank torque, screw lead, thread efficiency, cake diameter, seed charge and cake stiffness, then watch the platen descend and stall where the screw force balances the cake. Same screw-force relation as the 3D page, with the thread friction behind the efficiency and four in-page numerical checks.
