Rake (angle)

A rake is an angle of slope[1] measured from horizontal, or in some contexts from a vertical line 90° perpendicular to horizontal.

A 60° rake would mean that the line is pointing 60° up from horizontal, either forwards or backwards relative to the object.

Usage

Though the term may be used in a general manner, it is commonly applied in several specific contexts.

The rake of a ship's prow is the angle at which the prow rises from the water (the rake below water being called the bow rake). A motorcycle or bicycle fork rake is the angle at which the forks are angled down towards the ground.

In machining the rake angle is the angle from the cutting head to the object being worked on. In geology the rake is the angle at which one rock moves against another in a geological fault.

In a theatre or opera house the stage can be raked to slope up towards the back of the stage to allow better viewing for the audience.
