The core of the calculator relies on the specific coefficients defined by the WRC-1992 standard:
The calculator (a physical rotating disc) allowed the co-driver to input:
The calculator supports a wide range of components and mixtures, making it a versatile tool for various applications. I was also pleased to see that the software includes a built-in database of common components, which saves time and reduces errors.
Less common but equally vital, the "diagram" part of the calculator sometimes referred to a polar diagram of suspension roll centers. By inputting the lateral G-force expected in a diagrammed series of chicanes, the calculator wheel would suggest an anti-roll bar setting (soft/medium/hard) and a damper click value. This was cutting-edge for 1992, where active suspension was banned in WRC.
The is the modern industry standard used in welding metallurgy to predict the Ferrite Number (FN) and solidification mode of stainless steel weld metals . It serves as a more accurate successor to the older Schaeffler and DeLong diagrams by incorporating the effects of Nitrogen (N) and Copper (Cu) , which are critical for modern austenitic and duplex stainless steels. 🛠️ The WRC-1992 Calculation Formulas
