A Helical Spring
The helical spring, a type of spring in which wire is wrapped in a coil that resembles a screw thread, is probably the most commonly used mechanical spring. It can be designed to carry, pull, or push loads. Twisted helical (torsion) springs are used in engine starters and hinges. Helical tension and compression springs have numerous uses, notably automobile suspension systems, gun-recoil mechanisms, and closing valves on engines.
How to Calculate Spring Index of Engine Valve Spring given Shear Stress, Maximum Force and Wire Diameter?
Spring Index of Engine Valve Spring given Shear Stress, Maximum Force and Wire Diameter calculator uses Spring Index for Valve Spring = (pi*Shear Stress in Valve Spring*Wire Diameter of Valve Spring^2)/(8*Wahl Factor of Valve Spring*Axial Force on Valve Spring) to calculate the Spring Index for Valve Spring, The Spring Index of engine valve spring given shear stress, maximum force and wire diameter is defined as the ratio of the mean coil diameter of the engine valve spring to the diameter of the spring wire. Spring Index for Valve Spring is denoted by C symbol.
How to calculate Spring Index of Engine Valve Spring given Shear Stress, Maximum Force and Wire Diameter using this online calculator? To use this online calculator for Spring Index of Engine Valve Spring given Shear Stress, Maximum Force and Wire Diameter, enter Shear Stress in Valve Spring (fs), Wire Diameter of Valve Spring (dw), Wahl Factor of Valve Spring (K) & Axial Force on Valve Spring (P) and hit the calculate button. Here is how the Spring Index of Engine Valve Spring given Shear Stress, Maximum Force and Wire Diameter calculation can be explained with given input values -> 8.734667 = (pi*300000000*0.0055^2)/(8*1.2*340).
