#spring constant

The Scientific Research Notes Of S. Sunkavally (years: 2002-2011).

Hooke's Law states that the extension of a spring is directly proportional to the stretching force, with a constant k.

To verify Hooke’s Law, you can conduct a simple experiment using a spring and weights and follow the steps below. Apparatus A spring (helical coil spring) A support stand or clamp A ruler or measuring tape Weights (e.g., metal washers or masses) A balance or scale (optional, for measuring weights) Procedure: set the apparatus as shown One end of the spring is securely fixed to a support…

Finding the Spring Constant: A Model

This post is about my adventures in building a verifying a model for the stretch or compression of a spring. This involved using Hooke’s law and learning how to calculate the spring constant.

In my mathematical modeling book, there is a project that asks the reader to build a model that relates the stretch or compression of a spring to the mass it supports and then collect some data and find the…

Today we continued to assemble and diagnose problems occurring with the vibration lab apparatus. There is a major discontinuity in the springs - the spring constants seem to be different between each spring.

While part of this is probably due to the fact that the springs are cheap and therefore are likely not uniform, it is suspected that the spring mounts play a part in altering the constant of each individual spring, resulting in each apparatus behaving differently. 

The design of the spring mounts was changed to a smaller, thinner disc that could be welded to the spring, causing less of the spring to be used in it's mounting. Previously, the springs were mounted on small discs that had been screw cut on the lathe (by a previous co-op student) such that the springs could be twisted on. The idea behind welding the springs was that the spring constant variance would be greatly reduced between each spring, so that each apparatus would behave roughly the same.
