# Shear Centre - Channel Section

# Notation and Units

## Metric and Imperial Units

The above formulas may be used with both imperial and metric units. As with all calculations care must be taken to keep consistent units throughout with examples of units which should be adopted listed below:

# Notation

- b = width of flange (to centre of web), in or mm
- c = distance to shear centre, in or mm
- h = height of section (to centre of flanges), in or mm
- I = second moment of area, in
^{4}or mm^{4} - N/A = neutral axis
- t = flange thickness, in or mm
