| Topic in Mabie | Typical Problem | How to Check Your Answer | | :--- | :--- | :--- | | | 4-bar linkage angles | Use a free kinematic simulator (e.g., Linkage by Dave Billings, or MechDesigner ). Input your dimensions → compare your calculated angles. | | Velocity (Instant Centers) | Find angular velocity of a coupler | After finding instant centers manually, verify with a relative velocity polygon drawn to scale. The polygon’s closure is your answer key. | | Acceleration Analysis | Coriolis component | Most errors come from sign/direction. Redo the vector equation: ( \mathbfa B = \mathbfa A + \mathbfa B/A^t + \mathbfa B/A^n ). If your magnitude matches a known online example (from similar textbooks like Norton or Shigley ), you’re likely correct. | | Static Force (Friction) | Solve with friction circle | Compare your result to a simplified frictionless case first. The friction should reduce mechanical advantage by ~10-30% – a quick sanity check. | | Dynamic Force (D’Alembert) | Inertia forces in a slider-crank | Your inertia torque should be zero at dead centers. If not, re-check your acceleration polygon. |
