The following physical formula is known with the participation of the stiffness coefficient of the specified spring: F = k | x |, where F is the applied force, k is the coefficient of spring stiffness, and x is the elongation (narrowing), from where this formula is derived: k = F / | x |.
k = F / | x | = 245 N / 35 mm = 245 N / 0.035 m = 7000.
Answer: k = 7000.
