Tension springs are designed to operate under pulling forces, elongating when loaded, and typically have hooks for attachment. Compression springs work under pushing forces, shortening when loaded, and often have plain ends. Their load directions and end configurations differ fundamentally.
The spring rate (k) is calculated using the formula: k = (G * d^4) / (8 * D^3 * N), where G is the shear modulus of the material, d is the wire diameter, D is the mean coil diameter, and N is the number of active coils. This determines the force required per unit of elongation.
