Its used to determine stability or instability in a spring, and therefore the system its intended for. As long as a spring stays within its elastic limit, you can say that F = kx. How to Calculate a Spring Constant Using Hooke's Law. The mass m in kg & the spring constant k in N.m -1 are the key terms of this calculation. The effective mass of the spring in a spring-mass system when using an ideal spring of uniform linear density is 1/3 of the mass of the spring and is independent of the direction of the spring-mass system (i.e., horizontal, vertical, and oblique systems all have the same effective mass). Hooke's law is actually pretty limited. This problem might appear different to the previous examples, but ultimately the process of calculating the spring constant, k, is exactly the same. x = displacement. They inform you that the car will have a mass of 1,000 kilograms, and you have four shock absorbers, each 0.5 meters long, to work with. When two springs are connected in series, the result is essentially a longer and flimsier spring. Explain mathematic questions One plus one is two. How strong do the springs have to be? Answer 1) Given, Mass m = 5kg, Displacement x = 40cm = 0.4m. 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. As long as a spring stays within its elastic limit, you can say that F = kx. 0.035 m {\displaystyle 0.035m} If you push the spring, however, it pushes back, and if you pull the spring, it pulls back.\r\n
Hookes law is valid as long as the elastic material youre dealing with stays elastic that is, it stays within its . If you pull a spring too far, it loses its stretchy ability. This image may not be used by other entities without the express written consent of wikiHow, Inc. \n<\/p>

The spring constant is a property of the spring itself that shows the linear relationship between the force and the displacement. So, the spring will apply an equal and opposite load of -1N. The force resists the displacement and has a direction opposite to it, hence the minus sign. It does. This mass is displaced 0.7 meters below equilibrium and then launched with an initial velocity of 1 meters/second. 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 . He was a contributing editor at PC Magazine and was on the faculty at both MIT and Cornell. Its inclination depends on the constant of proportionality, called the spring constant. Tackling this problem is easy provided you think about the information youve been given and convert the displacement into meters before calculating. The spring-mass system can usually be used to find the period of any object performing the simple harmonic motion. F s = spring force. Understanding springs and their direction of force. Lee Johnson is a freelance writer and science enthusiast, with a passion for distilling complex concepts into simple, digestible language. Figure 2: The apparatus setup for the Hooke's . Where F is the force exerted on the spring in Newtons (N),. How to find the spring constant (example problem) F = mg = (250 kg)(9.8 m/s 2) = 2,450 N. where F equals force, m equals the mass of the object, and g equals the acceleration due to gravity, 9.8 meters per second 2. By using our site, you agree to our. k is the slope of the How to Calculate a Spring Constant Using Hooke's Law To find the spring constant as a function of displacement, just use Hookes law, F=-kx. How to Calculate a Spring Constant Using Hooke's Law. 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.The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium. In other words, if you pull on your length of spring and measure how much force it takes to stretch . Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.

The formula for Hooke's law specifically relates the change in extension of the spring, x , to the restoring force, F , generated in it: F = kx F = kx. But, if you continue to apply the force beyond the elastic limit, the spring with not return to its original pre-stretched state and will be permanently damaged. The spring constant, k, is representative of how stiff the spring is.Stiffer (more difficult to stretch) springs have higher spring constants. 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. When a spring stays within its elastic limit and obeys Hookes law, the spring is called an ideal spring. k = 588 The previous mass is detached from the spring and a mass of 14 kilograms is attached. Sure, you say. Solution: 1.Find out the force applied on the spring. Given: Mass m = 5kg. So, in my case its cm vs grams. Determining Spring Force The second is measuring period squared (T^2) vs mass. Each of the blue weights has a mass of 50 grams.
