STEP 1: Convert Input(s) to Base Unit

Collar Friction Torque for Power Screw: 10000 Newton Millimeter --> 10 Newton Meter (Check conversion here)
Outer Diameter of Collar: 100 Millimeter --> 0.1 Meter (Check conversion here)
Inner Diameter of Collar: 60 Millimeter --> 0.06 Meter (Check conversion here)
Load on screw: 1700 Newton --> 1700 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

μ_collar = (3*T_c*((D_o^2)-(D_i^2)))/(W*((D_o^3)-(D_i^3))) --> (3*10*((0.1^2)-(0.06^2)))/(1700*((0.1^3)-(0.06^3)))

Evaluating ... ...

μ_collar = 0.14405762304922

STEP 3: Convert Result to Output's Unit

0.14405762304922 --> No Conversion Required

FINAL ANSWER

0.14405762304922 ≈ 0.144058 <-- Coefficient of Friction for Collar
