This guide includes the definitions, standard formulas, calculation steps, and a worked example for a Rack and Pinion drive system. is the industry standard for practical application

• Calculating linear output force from input torque:
  F = (2 × T) / d
  where T = torque, d = pitch diameter
• Accounting for efficiency (η, typically 0.85–0.95)

• σ_b = bending stress (MPa)
• F_t = tangential force on tooth (N)
• b = face width (mm)
• m = module (mm)
• Y = Lewis form factor (depends on number of teeth and pressure angle; typical values: ~0.3 for 20° PA, 20 teeth)
