May 8, 2024 · You can use the Omni Calculator tool spring calculator or do as follows: Find out the applied torque. Remember that torque equals force multiplied by the distance of the lever arm. Measure how many degrees the spring has been twisted. Divide the torque by the twist angle. The result is the spring constant for a torsion spring, expressed in N·m/°.
Example for Applied Spring Force With A Real Part Number: For a coil spring with a spring rate of 6 lbf/in that needs to compress by 0.25 inches: F =6 lbf/in×0.25 in=1.5 lbs. This result tells us the force needed to compress the spring by 0.25 inches is 1.5 pounds.
Compression Spring calculator. Spring Calculator - Helical Compression. Helical (round wire) Spring calculator, for designing and manufacturing compression springs. To calculate the rate, enter the wire size, diameter and number of coils required to construct the spring.
If you have a coil spring that is required to travel 0.25" (inches) and has a spring rate of 6 pounds of force per inch (lbf/in), you must multiply the spring rate (k) of 6 lbf/in by the distance traveled (x) of 0.25"; the product will be the applied force required to meet your loaded height. Load = Rate x Travel. F = kx. F = 6 x 0.25. F = 1.5 lbs.
Calculate the force exerted by a conical spring with our Coil (Conical) Spring Force Calculator. Just input the wire diameter, mean coil radius, and shear modulus, and get instant results. Save time on your mechanical projects!
Calculation Formula. The coil (conical) spring force is calculated using the formula: \ [ F = \frac {\pi} {16} \cdot \frac {d^3} {r} \cdot t \] where: \ (F\) is the force in Newtons (N), \ (d\) is the diameter of the wire in meters (m), \ (r\) is the mean radius of the coil in meters (m), \ (t\) is the shear modulus of the material in Pascals (Pa).
