Stretch a spring, or a piece of metal, and it gets longer this relationship is explained in this video, along with a method of investigating the behaviour o. In this video, he claims that rubber bands do not act like springs by acting like springs of course he means hooke's law this essentially says that the more you stretch a spring, the greater. Department of aerospace engineering, indian institute of technology kanpur course: ae 681 composite materials instructor: pm mohite 3 it is seen that w is a quadratic function of strain a material with existence of w with property in eq. Honors lab physics- lab report objectives a to develop and verify hooke's law for springs - the amount that a spring stretches or compresses is directly proportional to the magnitude of the applied force.
Hooke’s law may also be expressed in terms of stress and strain stress is the force on unit areas within a material that develops as a result of the externally applied force stress is the force on unit areas within a material that develops as a result of the externally applied force. Solutions for the example problem from the topic of generalised hooke’s law for the solid mechanics i course. Stretch and compress springs to explore the relationships between force, spring constant, displacement, and potential energy investigate what happens when two springs are connected in series and parallel explain the relationships between applied force, spring force, spring constant, displacement.

Hooke's law says that the force produced by a spring is proportional to the displacement (linear amount of stretching or compressing) of that spring: f = -kx where k is called the force constant or spring constant of the spring. The spring: hooke’s law and oscillations 91 objectives • investigate how a spring behaves when it is stretched under the inﬂu-ence of an external force to verify that this behavior is accurately the mass will of course be acted upon by gravity, so the force exerted downward on the spring will be fg = mg (see fig 91. 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 see more.
(submitted as coursework for physics 210, stanford university, autumn 2007) by applying hooke's law in conjunction with newton's second law, it is possible to solve for the static equilibrium of a hanging slinky, and then use this result to solve for the motion of the slinky as it falls which is a direct result of hooke's law [4. Hooke’s law purpose: in this lab we will measure the spring constant of two springs using two di erent methods first, we will plot the force the spring exerts vs the distance the spring is stretched and second, we will measure the period. Behavior follows hooke's law to within the limits of accuracy of the experiment 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. Of course, hooke may have studied any one of these five works, or indeed, a combination of the texts perhaps the most interesting point to take away from this exercise is the popularity of euclid’s work and the range of translations and editions available to pupils at the school. Robert hooke was born in 1635 in freshwater on the isle of wight to john hooke and cecily gyles robert was the last of four children, in 1653, hooke (who had also undertaken a course of twenty lessons on the organ) secured a chorister's place at christ church, oxford.
Hooke’s law 1 purpose: 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 your goal will be to extract a measure of the stiffness of one particular spring 2 theory. Contributions to cell theory robert hooke's greatest legacy is his contribution to cell theorycell theory, as we know it today, is the result of the work of many different scientists. Robert hooke was an english philosopher, architect, and polymath hooke is known as one of the greatest experimental scientists of the seventeenth century with a broad scope of interest ranging from physics and astronomy to chemistry and biology, hooke invested many historic mechanical components. I cover sheet: this page has the course number and assigned lab section, the title of the experiment, your name, your lab partner’s names, the date that the lab was performed and your ta’s name ii “hooke's law” restoring force note that for simple harmonic motion, the period does not depend upon the amplitude of the oscillation.
Hooke college of applied sciences offers opportunities for college students to take our courses for undergraduate credit learn from experience learn from the experts. Robert hooke discovered the cell, established experimentation as crucial to scientific research, and did pioneering work in optics, gravitation, paleontology, architecture, and more yet history. Hooke’s law is a representation of linear elastic deformation elastic means that the spring will return to its original form once the outside force (the mass) is removed elastic means that the spring will return to its original form once the outside force (the mass) is removed. Published: thu, 01 feb 2018 investigating hooke’s law aim this experiment is aimed to investigate the relationship between the mass that is being slotted at the end of spring and the time taken for the spring to make a 20 complete oscillations.
The river hooke is a small river in the county of dorset in southern england it runs from its source at toller whelme through the villages and hamlets of hooke , kingcombe, toller porcorum and toller fratrum to join the river frome at maiden newton , a course of some 6 miles. Solutions for the problem question from the topic of generalised hooke’s law for the solid mechanics i course. The coursework’s system provides state-of-the-art online learning and information sharing tools, while creating a highly interactive educational experience.
If you are asking about what physical properties determine the value of hooke’s constant for a given spring, then there are a number of things that affect it: the material out of which the spring is made, of course - steel will be different than brass will be different than aluminum, etc the diameter of the material itself, a larger diameter will make a stiffer spring than a smaller diameter. This course explores the topic of solid objects subjected to stress and strain the methods taught in the course are used to predict the response of engineering structures to various types of loading, and to analyze the vulnerability of these structures to various failure modes axial loading with. Well, it's 2 times 2, it would be 4 4 newtons to displace it by 2 meters, and, of course, the restorative force will then be in the opposite direction, and that's where we get the negative number anyway, i've run out of time.
