Deflection for Close-Coiled Helical Spring Solution

Follow our step by step solution on how to calculate Deflection for Close-Coiled Helical Spring?

FIRST Step Consider the formula

δ = \frac{64 \cdot W load \cdot R^{3} \cdot N}{G Torsion \cdot d^{4}}

Next Step Substitute values of Variables

∴

δ = \frac{64 \cdot 85N \cdot {225mm}^{3} \cdot 9}{40GPa \cdot {45mm}^{4}}

Next Step Convert Units

∴

δ = \frac{64 \cdot 85N \cdot {0.225m}^{3} \cdot 9}{4E+10Pa \cdot {0.045m}^{4}}

Next Step Prepare to Evaluate

∴

δ = \frac{64 \cdot 85 \cdot {0.225}^{3} \cdot 9}{4E+10 \cdot {0.045}^{4}}

Next Step Evaluate

∴

δ = 0.0034m

LAST Step Convert to Output's Unit

∴

δ = 3.4mm
