The force-deflection relation of a steel helical spring used in an engine is found experimentally as F(x): 100 x + 30 x² + 5x³, where the force F and deflection x are measured in N and cm, respectively. If the spring undergoes a steady deflection of 0.3 cm during the operation of the engine, determine the equivalent linear spring constant of the spring at its steady deflection. =
