Jennifer holds a JD from Indiana University Maurer School of Law in 2006. . He was a contributing editor at PC Magazine and was on the faculty at both MIT and Cornell. which when substituted into the motion equation gives: Its spring force is reactive, which generates mechanical energy How much energy is represented by the spring constant. We created the Hooke's law calculator (spring force calculator) to help you determine the force in any spring that is stretched or compressed. 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. Ignoring the minus sign in Hookes law (since the direction doesnt matter for calculating the value of the spring constant) and dividing by the displacement, x, gives: Using the elastic potential energy formula is a similarly straightforward process, but it doesnt lend itself as well to a simple experiment. It is different for different springs and materials. The spring constant is 75 N m 75\,\dfrac{\text N}{\text m} 7 5 m N 75, start fraction, start text, N, end text, divided by, start text, m, end text, end fraction.

However, after the limit of proportionality for the material in question, the relationship is no longer a straight-line one, and Hookes law ceases to apply. 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. 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 elastic limit. If you pull a spring too far, it loses its stretchy ability. The load applied on the spring is 1N. You can see that if the spring isnt stretched or compressed, it exerts no force on the ball. It does. If you pull a spring too far, it loses its stretchy ability. Meaning, if the material returns to the dimension it had before the load or stress was applied, its deformation is reversible, non-permanent, and it springs back..

In order to figure out how to calculate the spring constant, we must remember what Hookes law says: Now, we need to rework the equation so that we are calculating for the missing metric, which is the spring constant, or k. Looking only at the magnitudes and therefore omitting the negative sign, you get, The springs used in the shock absorbers must have spring constants of at least 4,900 newtons per meter. In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distancethat is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring. Calculation Step by Step. where F equals force, m equals the mass of the object, and g equals the acceleration due to gravity, 9.8 meters per second2. On the other hand, compression corresponds to a negative value for x, and then the force acts in the positive direction, again towards x = 0. Determine the displacement of the spring - let's say, 0.15 m. Substitute them into the formula: F = -kx = -80 * 0.15 = 12 N. You can also use the Hooke's law calculator in. k is the spring constant, in Newtons per meter (N/m),.
