Spring Rate Calculator vs Diesel Cycle Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Spring Rate Calculator
Compute the spring rate (stiffness) of a helical compression spring from its wire and coil geometry. Use this during spring selection or custom spring design to match a required force-deflection characteristic.
- Answers
- Spring Rate (N/mm)
- Inputs
- Wire Diameter, Mean Coil Diameter, Number of Active Coils, Shear Modulus
Diesel Cycle Calculator
Compute the theoretical thermal efficiency of a Diesel engine cycle from its compression ratio and cut-off ratio. Use this to compare engine designs or understand how operating parameters limit maximum efficiency.
- Answers
- Diesel Cycle Efficiency (%)
- Inputs
- Compression Ratio, Cut-off Ratio
