Calculating Tension from Hz

Some equipment manufacturers will have a recommended frequency for the belt drive(s) in their system. As time goes on and components wear out, repairs/upgrades must be made to continue normal operation. Information like static belt pull is critical when calculating overhung/bearing loads especially when new components are introduced. To determine the static belt pull, the static tension must be known.

But how does one get there from Hertz?!

First we need to know a few characteristics about the belt drive.
Mass constant of the belt (g/m/mm of width)
Width of the belt (mm or #/ribs)
Span of belt (mm)

Each can be determined if unknown.

Using the following equation, tension can be determined.
