When a speed is provided, converts to L10h in operating hours. - [Belt Pulley Speed Ratio Calculator](https://elysiatools.com/en/tools/belt-pulley-speed-ratio): Calculate the ratio, driven speed and belt linear speed of a belt drive. i = d₂/d₁ = n₁/n₂, belt speed v = π·d·n/60. Supports mm/cm/m/inch diameter units. - [Bolt Torque Clamp Force Calculator](https://elysiatools.com/en/tools/bolt-torque-clamp-force): Convert between bolt tightening torque and axial clamp force. T = K·F·d, where K is the nut factor (~0.20 for dry steel). Solve torque from force, or force from torque. - [Cam Follower Displacement Calculator](https://elysiatools.com/en/tools/cam-follower-displacement): Calculate the follower displacement, velocity coefficient, acceleration coefficient and pressure angle during the cam rise phase. Supports constant-velocity, constant-acceleration, harmonic (SHM) and cycloidal motion laws. - [Chain Sprocket Ratio Calculator](https://elysiatools.com/en/tools/chain-sprocket-ratio): Calculate the ratio, driven speed and chain linear speed of a chain drive. i = z₂/z₁ = n₁/n₂, chain speed v = z₁·p·n₁/60000. Enter the pitch to compute chain speed. - [Flywheel Energy Storage Calculator](https://elysiatools.com/en/tools/flywheel-energy-storage): Calculate the kinetic energy stored in a flywheel. E = ½·I·ω², ω = 2π·n/60. Enter the moment of inertia directly, or compute it from flywheel mass and radius (I = ½·m·r²). Supports J/kJ/Wh. - [Gear Module Calculator](https://elysiatools.com/en/tools/gear-module-calculator): Calculate the gear module m. m = d/z = p/π. Solve the module from the pitch diameter d and tooth count z, or from the circular pitch p. Also returns the pitch diameter, circular pitch and addendum. - [Gear Ratio Calculator](https://elysiatools.com/en/tools/gear-ratio-calculator): Calculate the gear ratio and output speed of a meshing gear pair. i = z₂/z₁ = n₁/n₂. Enter the tooth counts to get the ratio; add the driver speed to get the driven speed. - [Gear Train Speed Ratio Calculator](https://elysiatools.com/en/tools/gear-train-speed-ratio): Calculate the overall ratio and output speed of a multi-stage gear train. i_total = i₁·i₂·…·iₙ (each i = z₂/z₁). Enter tooth pairs per stage and the input speed to get the final output speed. - [Lever Mechanical Advantage Calculator](https://elysiatools.com/en/tools/lever-mechanical-advantage): Calculate the mechanical advantage of a lever and its output force. MA = L_in / L_out, and by moment balance F_out = F_in · MA. MA > 1 saves force; MA < 1 saves distance. - [Mechanical Efficiency Calculator](https://elysiatools.com/en/tools/mechanical-efficiency-calculator): Calculate the efficiency of a mechanical transmission (gearbox, belt, chain, etc.). η = P_out / P_in, returning the efficiency percentage and the power loss P_loss = P_in − P_out. - [Moment of Inertia Calculator](https://elysiatools.com/en/tools/moment-of-inertia-calculator): Calculate the second moment of area (I) and section modulus (Z) for common cross-sections: solid circle, rectangle, hollow tube, and I-beam. Results in mm⁴ and cm⁴. - [Power Transmission Efficiency Calculator](https://elysiatools.com/en/tools/power-transmission-efficiency): Calculate the overall efficiency of a multi-stage transmission. η_total = η₁·η₂·…·ηₙ. Enter one stage efficiency per line (decimal, e.g. 0.98). Optionally add an input power to get the total loss and per-stage output power. - [Shaft Critical Speed Calculator](https://elysiatools.com/en/tools/shaft-critical-speed): Calculate the critical (resonance) speed of a rotating shaft using the single-DOF rotor model. ω_n = √(k/m), n_cr = (60/2π)·√(k/m) rpm. Also returns the natural frequency f_n in Hz. - [Shaft Power Calculator](https://elysiatools.com/en/tools/shaft-power-calculator): Calculate the power transmitted by a rotating shaft. P = T·ω = 2π·n·T/60. Solve power from torque and speed, or torque from power and speed. Supports W/kW/hp. - [Spring Compression Energy Calculator](https://elysiatools.com/en/tools/spring-compression-energy): Calculate the elastic potential energy and force of a spring in compression or extension. U = ½·k·x², F = k·x. Solve energy from displacement, or displacement from energy. - [Spring Rate Calculator](https://elysiatools.com/en/tools/spring-rate-calculator): Calculate the stiffness (spring rate) of a cylindrical helical compression/extension spring. k = G·d⁴ / (8·D³·n) in N/mm.
