K = \frac{3.1416 \cdot 300N/mm² \cdot {5.5mm}^{2}}{8 \cdot 8 \cdot (120N + 9N/mm \cdot 11mm)}

Next Step Convert Units

∴

K = \frac{3.1416 \cdot 3E+8Pa \cdot {0.0055m}^{2}}{8 \cdot 8 \cdot (120N + 9000N/m \cdot 0.011m)}

Next Step Prepare to Evaluate

∴

K = \frac{3.1416 \cdot 3E+8 \cdot {0.0055}^{2}}{8 \cdot 8 \cdot (120 + 9000 \cdot 0.011)}

Next Step Evaluate

∴

K = 2.03410055160726

LAST Step Rounding Answer

∴

K = 2.0341
