Robert Hooke law 1660. By measuring the mass of the system and its period of oscillation, the value of the spring constant can be . Calculating percentage deviation . This is a function that should be used to introduce new ply level materials within a laminate analysis. So: At equilibrium , F r = F In other words, he discovered that elastic materials like coiled springs stretch proportionately . Alaa Khoja , ID: 25881612 HOOKE'S LAW AND MATERIAL'S BEHAVIOR. By Hooke's law, F = - kx. It states that the material's deformations are directly proportional to the externally applied load on the material. Springs behave like Hookean Materials. It is supported by the formula of force, F = kx, where F is the applied force, k is the spring . Since x is in the negative y direction the value for k will be positive. Upon further analysis, it can be seen that the gradient for y2 is greater than that of y1 as the value of "a"for the equation of y2 is larger. Figure 1: Proportionality according to the Hooke's Law . Hooke's Law In the diagram below is shown a block attached to a spring. Set up the spring as figure 4.2 2.Measure the length of each spring Lthin L thick 3. k = 62.5 Nm-1. The variables of the equation are F, which represents force, k, which is called the spring constant and . 124 Physics Lab: Hooke's Law and Simple Harmonic Motion According to the Hooke's Law: "Within the limit of proportionality, the extension of a material is proportional to the applied force" (Bird & Ross, 2012). Hooke's Law is a law that shows the relationship between the forces applied to a spring and its elasticity. Most of Hooke's discoveries resulted from careful observations and measurements. Hooke's law can be expressed as. Elastic force acts in the opposite direction of the external force. k = 1/0.016. The spring constant k depends on the material and the geometric dimensions of the spring. For a cylindrical coil spring . Hooke's Law | A Level Notes References; 1. PDF Experiment 2: Hooke's Law - GitHub Pages PDF Physics 110 Lab 3: Hooke's Law & Oscillations See fig. The force can easily be calculated by hanging it at the end of an attached string then, using the equation weight = mass x gravity (F = mg). Calculating percentage deviation . According to Hooke's law, this restoring force is proportional to 'x' and oppositely directed. In position (B) a force F is used to compress the spring by a length equal to Δ x by pushing the block to the left. The spring constant can be determine by using the formula of Hooke;s law; F = kx. This paper describes the framework and methodology for the creation of a Remote Triggered Virtual Laboratory experiment for teaching Hooke's Law, a key .
