Spring Calculator Module
Extension Spring Calculator
Design helical extension springs with various hook configurations (Machine, Cross, Side). Calculate spring rate, initial tension, and stress at both body and hooks.
Extension Spring
Spring rate is computed from the body coils using the same formula as compression springs. Total Load = Initial Tension + k·Δx.
Input parameters and run the calculation to view spring rate, load, and stress results.
