Torque Torque Torque, moment, or moment of force is the rotational equivalent of linear force. The concept originated with the studies of Archimedes on the usage of levers. Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object. The symbol for torque is typically formula_1, the lowercase Greek letter "tau". When being referred to as moment of force, it is commonly denoted by "M". In three dimensions, the torque is a pseudovector; for point particles, it is given by the cross product of the position vector (distance vector)
Apache Torque Apache Torque Apache Torque is a sub project of the Apache Software Foundation Database Project. It is an object-relational mapper for Java. Torque lets you access and manipulate data in a relational database using Java objects. Unlike most other object-relational mappers, Torque does not use reflection to access user-provided classes, but it generates the necessary classes (including the Data Objects) from an XML document and DTD describing the database schema (which can either be written by hand or generated from an existing database). The same XML documents can also be used to generate and execute a SQL script which creates
