1. The problem statement, all variables and given/known data I'm trying to find a relationship between spring and torsion constants for an experiment but am not sure what it is and am struggling to find it. 2. Relevant equations Torque = Torsion Constant * Angle of Twist Force = Spring Constant * Extension Shear Modulus = Force*Length/Area*Extension 3. The attempt at a solution I have absolutely no idea.
