## Current project goals

1. Investigate the global in-plane rigid body rotation of the GSM utilizing Digital Image Correlation (DIC).

2. Determine vital parameters that significantly displace the GSM

• Determine velocity dependence

-At a constant plane, vary the velocity of the circular path to determine if they affect the rotation linearly

• Determine diameter dependence of inner region

-At a constant plane, vary the diameter of the circular path to determine if they affect the rotation linearly

• Determine the depth dependence on the inner rotation

- With constant needle velocity and diameter of the circular path, use the DIC at various planes to understand the displacement due to depth

- At a constant plane, vary the velocity and diameter of the circular path to determine if they affect the rotation linearly
