Engineers use a “nut factor” to relate a bolt’s installation torque to the tension on it. But they need to understand the friction-related variables that contribute to the nut factor to ...

Today I want to share one of the most important equations to keep in mind when ... are both flexible and do not stretch when put in tension. Since these cables are flexible, they can only exhibit ...

Calculating tight and slack side tensions and shaft forces (two equations, three unknowns) for a given torque or effective tension, requires an additional relationship: belt elongation.
