Mixing 101: Torque and the Art of Mixing

Oct 20, 2015Mathematically speaking, torque is defined as the lever arm vector (distance) multiplied by the applied force vector (force), which tends to produce rotation on an axis. Torque can be explained through a simple demonstration of force applied to a lever. Given a standard amount of input force, a longer lever means a greater amount of torque Get price
