Mechanical
Friction Force Calculator
Calculates the friction force resisting relative motion between two surfaces from the normal force and the coefficient of friction. Use it in braking, clamping, or sliding contact design problems.

Mechanical
Screw Torque Calculator
Calculates the torque needed to clamp a fastener to a target axial force, accounting for thread geometry and friction. Use it when tightening critical bolted joints to avoid under- or over-torquing.
