What type of torque is defined as the amount needed to move the load?

The term that defines the amount of torque needed to initiate movement of a load is known as breakaway torque. This is particularly significant in mechanical systems where static friction must be overcome to start the motion of an object. Breakaway torque is the minimum torque required to break loose a stationary object and set it in motion. Once the load is in motion, it may require a different amount of torque to keep it moving, which is typically less due to reduced resistance. This distinction highlights the importance of understanding how different types of torque apply to various stages of load movement, particularly in pneumatic and mechanical systems.

Understanding the role of breakaway torque is crucial for designing systems that can efficiently start motion and manage loads effectively. This ensures that motors and pneumatic systems are adequately sized for both starting and running conditions, thereby preventing potential system failures or inefficiencies.
