Free length of a spring
WebThis spring has a 6” (inch) free length, a spring rate of 10 lbf/in (pounds of force per inch), and travels 0.1” (inches) under pre-load. So, how much pre-load is being applied to this compression spring? Formula. WebThen, you must divide the free length of spring by the mean diameter. The result of this equation will be written as x:1 (x to 1) describing the proportion being made to 1 mean diameter as shown in the example to the right. …

Lengths of legs are shown as "A" in sketches below. Please note: "R" (radius in inches) where force is applied is always 1/2 of "A" (Length of Leg).
WebThis formula requires more information than the previous. The material type and its properties have a lot to do with your spring’s rate. D = D outer – d. G = E ÷ 2 (1 + V) k = Gd^4 ÷ (8D^3 x na) d = Wire Diameter. D outer = Outer Diameter. D = Mean Diameter. E = Young's Modulus of Material. WebWhen the free height of the spring ( Lfree) is more than 4~5 times the nominal coil diameter D, the spring can buckle under a sufficiently heavy load. The maximum allowable spring deflection D max that avoids buckling depends on the free length, the coil diameter, and the spring ends (pivot ball, ground & squared, etc.).
WebWithin certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke's law and commonly written: \boxed {F=-kx} F = −kx. Where F F is the force, x x is the length of extension/compression and k k is a constant of proportionality known as ...
WebSpring Geometry. The rise angle of the spring coils (the angle between the coils and the base of the spring) is found from the arctangent of the coil-pitch divided by the spring circumference, The solid height of the spring is found by summing the widths of all the spring coils.
