Brabender Plastograph
{{Unreferenced, date=March 2020 The ''plastograph'', or Brabender plastograph, is a device for the continuous observation of torque in the Shearing (physics), shearing of a polymer with a range of temperatures and shear rates. The generic device records lubricity, Plasticity (physics), plasticity, Scorching (physics), scorch, Curing (chemistry), cure, Shearing (physics), shear, and heat stability. Perhaps the most popular use of the plastograph is its use in baking where it is known as a Farinograph. It was designed by Carl Wilhelm Brabender and produced by Brabender Industries, founded in 1923. External links Official website

Torque
In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force (also abbreviated to moment). It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "''Give me a lever and a place to stand and I will move the Earth''". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . In ...
