EVA Glove Grip Fatigue Simulator

Every EVA glove fights the astronaut's own hand: suit pressure keeps the fabric joints straight, so closing a fist to turn a stuck valve means overcoming a resistance torque before any useful work gets done. This simulator models that pressurized-glove biomechanics directly — a simplified glove-joint torque model set against a Rohmert-style muscle fatigue curve — and drives a 3D gloved hand repeatedly gripping a valve wheel. Tune suit pressure, grip effort and task cadence and watch net torque, cumulative hand fatigue and the wheel's turn count respond exactly as the underlying equations dictate, including the point where a tired hand simply can't win against its own suit anymore.
