Weight test

Parameter values:

.765 lbs. via Solid Works

Calculated Values:

.726 lbs. using scale

Success Criteria values:

.865 lbs. Spark R&D Dyno binding.

Conclusion: The ultra-light split board binding exceeded the success criteria values by 16%.

Ride Test

Parameter values:

.000” of permanent deflection

Calculated Values:

.000” of permanent deflection

Success Criteria values:

0-.005” permanent deflection

Conclusion: The binding system had no permanent deflection from ride testing.

Compressive Test

 Parameter values:

   Channel 1 Max         53,055 psi ,  53,825 psi

   Channel 2 Max        19,765 psi   , 19,500 psi

   Channel 3 Max         15,765 psi ,  15,740 psi

Calculated Values:

Channel 1 Max

41,582psi

Success Criteria values

Below Yield strength values of 7075 T6 aluminum at 73,000 psi

Conclusion: The only value that is conclusive and matters in this test is channel one because it has the least amount of cross sectional area about the bending axis. Values are lower in the calculated because the moment of inertia was changed when a hole was drilled for the clevis Pin increasing stress concentrations.
