Question

Figure 1 shows the suspension system of a freight truck with a parallel-spring arrangement. Find the equivalent spring constant (one side only, i.e., three springs) of the suspension if each of the three helical springs is made of steel with a shear modulus G = 80x10^9 N/m² and has five effective turns, mean coil diameter D = 20 cm, and wire diameter d = 2 cm. Figure 1: Parallel arrangement of springs in a freight truck.

Step 1

Given: G = 80 x 10^9 N/m^2 d = 0.02 m D = 0.2 m Plugging in the values: K = (80 x 10^9 * (0.02^4) / (8 * 0.2^3)) * N K = (80 x 10^9 * 1.6 x 10^-8 / (8 * 0.008)) * N K = (128 x 10^1 / 0.064) * N K = 2000 N Show more…
