1 S1. See Figure 1: Functional Sketches attached at the end S2. Motion with a torsion spring is linear but follows an axis of rotation and results in circular motion and circular resistance from the spring. When a torsion spring is compressed, the motion of the spring is restricted to the axis of rotation. Motion with a tension or compression spring is also linear along the axis of the spring. When force is applied to a compression or tension spring, the motion of the object is only linear. S3. Depending on how the flat spring is manipulated, it could be used as a compression, tension, or torsion spring. To obtain a compression spring, the flat spring would be folded over in half less than 180˚ so that the spring would apply forces in opposite linear directions when outside forces act inward towards the fold because the flat spring would want to return to its original flat position. To obtain a tension spring, the flat spring would be folded more than 180˚ so that the spring would apply forces towards each other when opposing forces are applied because the spring has a tendency to return to its original state. To obtain a torsion spring, the flat spring would be coiled up so that the forces from the spring would be applied in opposite directions and along the axis of rotation. See Figure 2: Flat Spring Configurations attached at the end for sketches of configurations. S4. Figure 3: Weight vs. Change in Spring Length Plot Change in spring length and weight applied to the spring are directly proportional to each other. As the weight applied to the spring increases the change in spring length from the original
