| Under the force of 320 N, the shock absorber spring was compressed by 9 mm. How many millimeters will the spring be compressed under a load of 1.6 kN?
F1 = 320 N.
x1 = 9 mm = 0.009 m.
F2 = 1.6 kN = 1600 N.
x2 -?
When the spring is compressed, the load force F is compensated by the elastic force Fcont, which occurs in the spring: F = Fcont.
F1 = Fcont1.
F2 = Fcont2.
According to Hooke’s law, the elastic force Fel is directly proportional to the elongation of the spring: Fel = k * x, where k is the stiffness of the spring.
F1 = k * x1.
F2 = k * x2.
x2 = F2 / k.
k = F1 / x1.
x2 = F2 * x1 / F1.
x2 = 1600 N * 0.009 m / 320 N = 0.045 m.
Answer: the shock absorber spring will be compressed by x2 = 0.045 m under the load.
