trinnvinkler

Trinnvinkler is a Norwegian term that denotes a set of angular measurements associated with discrete steps or levels in a system. The compound noun combines trinn (step, level) and vinkler (angles) and is used in various technical contexts where an object or path advances or rotates in defined increments. Because it is context-dependent, the exact meaning varies by field.

In mechanical engineering and robotics, trinnvinkler commonly describe the angular increments of devices that move in steps, such as stepper motors or rotary encoders. If a rotor completes a full revolution in k equal steps, the trinnvinkel is Δ = 360°/k (or 2π/k radians), and the sequence of step angles is θ_i = iΔ for i = 0,...,k−1.

In computer graphics and kinematics, trinnvinkler can refer to the set of discrete directions in a polyline or chain where each segment changes direction by a fixed angle. In architecture and stair design, the term may be used less formally to discuss the angular geometry that results from successive treads, though terms like pitch or slope are more common.
