Mechanical Engineering Calculators for Machine Design
Bolt tightening torque, bearing fatigue life, cable bending radius, servo regeneration, and machine motion review calculators.
Recommended workflow
- Start from load, speed, torque, or geometry
- Check the formula assumptions and units
- Confirm final selection with manufacturer ratings
Start from the field problem
Choose the symptom or design decision first. Each path leads to the calculation, assumptions, and next verification step.
The 24V power supply runs hot
Sum loads, apply diversity and temperature derating, then compare alternatives.
A motor trips during startup
Separate full-load current from inrush current and review protection coordination.
A 4-20mA signal is unstable
Check loop voltage margin, wiring, grounding, input-card range, and measured values.
The control cabinet temperature rises
Estimate heat load, ambient conditions, fan or AC capacity, and derating needs.
Bolt Tightening Torque Calculator for Metric Fasteners
Estimate tightening torque from bolt diameter, preload, grade, and friction coefficient for preliminary mechanical assembly review.
Bearing L10h Fatigue Life Calculator Using ISO 281 Method
Estimate bearing fatigue life from dynamic load rating, equivalent load, speed, and operating assumptions.
Cable Bending Radius and Cable Carrier Calculator
Calculate minimum cable bending radius and cable-carrier clearance for moving industrial cables and drag-chain applications.
