Hookes law is a law of physics that states that the force f needed to extend or compress a. This means that the extension of the sample increases linearly with the amount of force applied. The shape of a body will distort when a force is applied to it. Hookes law states that, for certain elastic materials, force is proportional to extension, when a sample is stretched. Hookes law is a principle of physics that states that the that the force needed. This lab is set up for us to to be able to determine the spring constant with two different methods and the gravitational acceleration with a pendulum.
Your goal will be to extract a measure of the stiffness of one particular spring. It is the general question that is asked in the subject strength of materials. The number of coils per unit of spring length was the same for all springs. Hookes law introduction force of a spring flipping physics. Hookes law in terms of stress and strain is strain stress. A formal lab report should include a title page like this one, with all of the appropriate information a descriptive title, your name, the course title, the date, and an abstract. Elastic behaviour of solids according to hookes law can be explained by the fact. Hookes law, law of elasticity that relates the size of the deformation of an object to. Hookes law is a principle of physics that states that the that the force. Einsteins theory of special relativity 1905 shows that matter as mass and. Hooke s law definition, the law stating that the stress on a solid substance is directly proportional to the strain produced, provided the stress is less than the elastic limit of the substance. Hookes law definition of hookes law by merriamwebster. The primary purpose of the lab is to study hooke s law and simple harmonic motion by studying the behavior of a mass on a spring. An rubber band is stretched from its resting position a distance of 0.
Hooke s law is a principle of physics that states that the that the force needed to extend or compress a spring by some distance is proportional to that. Model to demonstrate hookes law and illustrate that physiological. The spring wire had circular section with a diameter of 0. Springs come in a huge variety of different forms, but the simple metal coil spring is probably the most familiar. Hooke s law is the first classical example of an explanation of elasticity which is the property of an object or material which causes it to be restored to its original shape after distortion.

F s, the force of the spring is opposite the direction of. Hooke s law physics the principle that the stress applied to a solid is directly proportional to the strain produced. This law describes the behavior of springs and solids stressed within their elastic limit.
A historical reconstruction of what robert hooke looked like, painted in 2004 by. This law gives us a relation between stress and strain. It looks like the previous definition but the picture below shows otherwise. The deforming force may be applied to a solid by stretching, compressing, squeezing, bending, or twisting.
