TF outer leg OOP Lorenz force (about 1/3 of power limit condition)Scenario 79: 106KNRadius rods (spring) and supports (ss): 2”x2”Radius rod length: 23.4” (0.595m)Ring (ss): 1”x4”Cylindrical coordinate: model Z is machine vertical axis, model X is radial and Y is theta direction.

If using clevis shear load of 8klbs as a criteria, radius modulus of 800MPa can meet the requirement and corresponding spring stiffness is 19.85 klbs/in.
