Calculate the basic rating life of a rolling bearing: L10 = (C/P)^p, with p = 3 for ball bearings and p = 10/3 for roller bearings. When a speed is provided, converts to L10h in operating hours.

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.

Compare SRT or WebVTT cue timing with likely speech activity and flag timing drift.
audio-caption-sync-checkerMedia
Find likely simultaneous speech-like activity by detecting multiple balanced voice-frequency bands.
audio-overlap-speech-detectorMedia
Mark likely acoustic turn changes in speech-range audio and export an approximate turn timeline.

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.
belt-pulley-speed-ratioMath & Numbers
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.
bolt-torque-clamp-forceMath & Numbers
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.
