Adjective

radial (comparative more radial, superlative most radial)

1. Arranged like rays that radiate from, or converge to, a common centre.

   The spokes on most modern bicycle wheels are tangential to the hub rather than radial.

   • 2012 March, Henry Petroski, “Opening Doors”, in American Scientist‎^[1], volume 100, number 2, pages 112–3:

     A doorknob of whatever roundish shape is effectively a continuum of levers, with the axis of the latching mechanism—known as the spindle—being the fulcrum about which the turning takes place. Applying a force tangential to the knob is essentially equivalent to applying one perpendicular to a radial line defining the lever.

2. (geometry) Of, or relating to a radius (line joining to a geometric centre).

   What is the relationship between arc length and radial length?

   1. Moving or acting along a radius.
