Bolt torque from preload

Estimates bolt preload from tightening torque, nut factor K, and nominal diameter.

Calculates average bolt stress as preload divided by tensile stress area.

Calculates bolt stiffness, load-share factor, bolt load increase, remaining clamp force, and separation flag.

Calculates separation load from preload and the stiffness-based load-share factor.

Calculates average bearing pressure from force, bolt diameter, and plate thickness.

Calculates bolt safety factor as allowable stress divided by actual stress.
