= k d4G8D3N The spring dimensions measured during the lab are shown in Table 2. The theoretical values of the spring coefficient is calculated by using the spring equation given, and the shear modulus of common steel used in spring 11600 ksi. It is calculated to be 674.69 lb/in. Table : Spring Experiment Weight Applied Spring Length Spring Displacement 0 0.735 0 25 0.756 0.021 50 0.797 0.062 75 0.811 0.076 100 0.846 0.111 According to the experiment, the force applied to the spring and the corresponding spring displacements were measured. The relationship between the force and displacement is linearly plotted in the figure 1.

Unformatted text preview: The value of the spring coefficient is the slope of the linear graph which was calculated to be 887.59 lb/in. This value is greater than the theoretical spring value that we calculated. This discrepancy could be because of the unknown friction that may occurred during the experiment or the shear modulus used in the theoretical spring constant calculation was different from that of the material used during the experiment....
