Screw theory

nounStandard termMechanical

A mathematical framework used to describe the kinematics and dynamics of rigid bodies.

An algebraic method that combines linear and angular vectors into a single geometric entity called a screw. It simplifies the analysis of complex spatial mechanisms, robotics, and multi-body systems by treating translation and rotation simultaneously. This approach allows engineers to calculate forces, velocities, and joint constraints with fewer equations than traditional vector mechanics.
