What is torque stiction?

Torque stiction refers to the resistance to motion that occurs when a stationary object experiences an initial torque force. This phenomenon is particularly relevant in mechanical systems, such as bearings or gears, where static friction must be overcome to initiate movement. Once the applied torque exceeds the stiction threshold, the object begins to move, often leading to a sudden jump in motion. This can result in mechanical wear and affect performance in various applications.
