  1. A torsion spring has the following conditions:
  • Moment load = 3.0 in-lb; Spring OD = 0.6”; 1/8” wire diameter; Squared and ground ends; 5 body turns; Material is music wire; Both end lengths = 0.75”

Answer the following:

What is the safety factor with respect to stress? (N=can do/doing=allowable stress/induced stress)

How much does the spring rotate, in units of degrees?
