Mechanical Engineering Calculators & Design Tools
Free mechanical engineering calculators for statics, strength of materials, dynamics, vibration, machine design, stress, deflection, shafts, gears, and engineering mechanics.
Explore Mechanical
Use mechanical engineering calculators and workbenches for statics, strength of materials, dynamics, vibration, and machine design. The tools connect free-body relationships, stress and deflection equations, motion, and component sizing.
Results are intended for learning and preliminary analysis, with equations and engineering assumptions exposed for verification.
