| Ball MOI RatioRatio of MOI to mass times radius squared. 2/5 for a solid sphere, 2/3 for a hollow sphere, 1/2 for a solid cylinder, 1 for a hollow cylinder. |
+/- | [-] | ||
| Ball StiffnessStiffness of the ball. This should be evaluated as a shock condition and near the amount of compression in the case of nonlinear balls (which, practically any ball will be) | +/- | |||
| Wheel Diameter | +/- | |||
| Wheel MOI | +/- | |||
| Hood Gap | +/- | |||
| Hood StartAngle that the hood starts at, with respect to vertical. A larger value would mean the hood wraps around more. |
+/- | |||
| Hood EndAngle that the hood ends at, with respect to vertical. This would be the same as the release/departure angle with respect to the horizontal. A larger value would mean that the hood wraps around less, and creates a more vertical shot. |
