The forced oscillation frequency is 2Hz. What is the mass of a load on a spring with a stiffness of 100N / m?

To determine the value of the mass of the load on a given oscillating spring, we use the formula: ν = 1 / 2Π * √ (k / m), whence we express: k / m = ν2 * 4 * Π2 and m = k / (ν2 * 4 * Π2).
Variables: k – stiffness of the oscillating spring (k = 100 N / m); ν is the frequency of forced oscillations (ν = 2 Hz).
Calculation: m = k / (ν * 4 * Π2) = 100 / (22 * 4 * 3.142) = 0.634 kg.
Answer: The mass of the load on a given oscillating spring is 0.634 kg.
