Hooke's law is based on Newton's third law of motion, which states that for every action there is an equal and opposite reaction. The mass is 0.4-kilogram and the spring constant is 1.2 Newtons per meter. \begin{aligned} k&=\frac{F}{x} \\ &= \frac{6\;\text{N}}{0.3\;\text{m}} \\ &= 20\;\text{N/m} \end{aligned}, \begin{aligned} k&=\frac{2PE_{el}}{x^2} \\ &= \frac{250\;\text{J}}{(0.5\;\text{m})^2} \\ &=\frac{100\;\text{J}}{0.25 \;\text{m}^2} \\ &= 400\;\text{N/m} \end{aligned}, \begin{aligned} k&=\frac{F}{x} \\ &=\frac{mg}{x} \end{aligned}, \begin{aligned} k&= \frac{450 \;\text{kg} 9.81 \;\text{m/s}^2}{0.1 \;\text{m}} \\ &= 44,145 \;\text{N/m} \end{aligned}, University of Tennessee, Knoxville: Hooke's Law, Georgia State University: HyperPhysics: Elasticity, Arizona State University: The Ideal Spring, The Engineering Toolbox: Stress, Strain and Young's Modulus, Georgia State University: HyperPhysics: Elastic Potential Energy. In order to figure out how to calculate the spring constant, we must remember what Hookes law says:\r\n\r\nF = kx\r\n\r\nNow, we need to rework the equation so that we are calculating for the missing metric, which is the spring constant, or k. wikiHow is where trusted research and expert knowledge come together. They are a necessary component for a wide variety of mechanical devices. What does this mean the spring constant should be? As a formula, it reworks Hooke's Law . The frequency of the vibration is f = /2. Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its elastic limit. When force is applied to stretch a spring, it can return to its original state once you stop applying the force, just before the elastic limit. Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its elastic limit. The value of this constant depends on the qualities of the specific spring, and this can be directly derived from the properties of the spring if needed. When the force that causes the deformation disappears, the spring comes back to its initial shape, provided the elastic limit was not exceeded. Here's how you can derive this equation. To find the spring constant, we first need to find the force that is acting on the spring. As long as a spring stays within its elastic limit, you can say that F = kx.

Dr. Steven Holzner has written more than 40 books about physics and programming. When you compress or extend a spring or any elastic material youll instinctively know whats going to happen when you release the force youre applying: The spring or material will return to its original length. In a compression compression springs, deflection is caused by twisting the wire diameter, and therefore the spring constant (k) is as follows. Answer 1) Given, Mass m = 5kg, Displacement x = 40cm = 0.4m. Find the mass of the block of wood. How strong do the springs have to be? Which of the following equipment is required for motorized vessels operating in Washington boat Ed? 0.1 N {\displaystyle 0.1N} and the distance the spring stretches when that force is added is. He was a contributing editor at PC Magazine and was on the faculty at both MIT and Cornell. As long as a spring stays within its elastic limit, you can say that F = kx. Then the applied force is 28N for a 0.7 m displacement. If we hang a mass from a spring and measure its stretch, how can we determine the spring constant?HW K 10 14. The spring in the shock absorber will, at a minimum, have to give you 2,450 newtons of force at the maximum compression of 0.5 meters. The equation for elastic potential energy relates the displacement, x, and the spring constant, k, to the elastic potential PEel, and it takes the same basic form as the equation for kinetic energy: As a form of energy, the units of elastic potential energy are joules (J). F = 150 0.8. You can see that if the spring isnt stretched or compressed, it exerts no force on the ball. Our goal is to make science relevant and fun for everyone. Plug the values for the second weight into the formula to find the spring constant: [11] The formula to find the spring constant is. The concept of elastic potential energy, introduced alongside the spring constant earlier in the article, is very useful if you want to learn to calculate k using other data. How to Calculate a Spring Constant Using Hooke's Law. 0.035 m {\displaystyle 0.035m} Solution: 1.Find out the force applied on the spring. The only other forces exerted on the mass are .

Which fitt principle variable is changed when you increase the length of the physical activity, A nurse is providing teaching to a client who has hypothyroidism and is taking levothyroxine. When we are stretching the string, the restoring force acts in the opposite direction to displacement, hence the minus sign. In Hookes law, the negative sign on the springs force means that the force exerted by the spring opposes the springs displacement. Each of the blue weights has a mass of 50 grams. Which of the following is an advantage of organizational culture? By timing the duration of one complete oscillation we can determine the period and hence the frequency. The variables of the equation are F, which represents force, k, which is called the spring constant and measures how stiff and strong the spring is, and x, the distance the spring is stretched or compressed away from its equilibrium or rest position. In any situation where you need to calculate the response of an object to a force you use Newton's second law. {"appState":{"pageLoadApiCallsStatus":true},"articleState":{"article":{"headers":{"creationTime":"2016-03-26T17:23:25+00:00","modifiedTime":"2021-10-29T19:44:00+00:00","timestamp":"2022-09-14T18:18:44+00:00"},"data":{"breadcrumbs":[{"name":"Academics & The Arts","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33662"},"slug":"academics-the-arts","categoryId":33662},{"name":"Science","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33756"},"slug":"science","categoryId":33756},{"name":"Physics","_links":{"self":"https://dummies-api.dummies.com/v2/categories/33769"},"slug":"physics","categoryId":33769}],"title":"How to Calculate a Spring Constant Using Hooke's Law","strippedTitle":"how to calculate a spring constant using hooke's law","slug":"how-to-calculate-a-spring-constant-using-hookes-law","canonicalUrl":"","seo":{"metaDescription":"Learn about Hooke's law and how to calculate the spring constant, including the formula and insight on a spring's impact on force. b. The only additional step is translating the mass of the car into a weight (i.e., the force due to gravity acting on the mass) on each wheel. He was a contributing editor at PC Magazine and was on the faculty at both MIT and Cornell. The proportional constant k is called the spring constant. The unloaded length of a spring is measured. The Period of a Mass-Spring System calculator computes the period () of a mass-spring system based on the spring constant and the mass.
