		The forces are primarily generated in the orofacial/craniofacial complex by muscle, body posture, skeletal alignment, body function and the anatomy of the teeth.
		In an ideal model, when all the forces are balanced, the body is balanced and the resultant force vector is zero (neutral).
		The muscle tension produced is relative to the resultant force vector that is generated and the adaptive capacity of the patient.

	Force - Wikipedia, the free encyclopedia
		Conservative forces are equivalent to the gradient of a potential, and include gravity, electromagnetic force, and spring force.
		This condition is called static equilibrium, with the result that the object remains at rest or moves with a constant velocity.
		This superposition of forces, and the definition of inertial frames and inertial mass, are the empirical content of Newton's laws of motion.

	Net force - Wikipedia, the free encyclopedia
		A net force (also known as a resultant force) is a vector produced when two or more forces act upon a single object.
		It is calculated by adding the force vectors acting upon the object.
		When force A and force B act on an object in the same direction (parallel vectors), the net force (C) is equal to A + B, in the direction that both A and B point.

		Suppose that a force board or a force table is used such that there are three forces acting upon an object (the object is the ring in the center of the force board or force table).
		For the situation of the three forces on the force board, the net force is the sum of force vectors A + B + C. One method of determining the vector sum of these three forces (i.e., the net force") is to employ the method of head-to-tail addition.
		For this example, the minimum magnitude for the resultant is 0 Newtons (occurring when 10 N and 10 N are in the opposite direction); and the maximum magnitude for the resultant is 20 N (occurring when 10 N and 10 N are in the same direction).

	Coplanar Force Resolution
		The resultant is a representative force which has the same effect on the body as the group of forces it replaces.
		When forces are being represented as vectors, it is important to should show a clear distinction between a resultant and its components.
		It is equal in magnitude, opposite in sense and co-linear with the resultant.

		At frame B the resultant force is approximately 70 degrees to the radius at the biceps brachii insertion and suggests F1 is considerably larger than F2.
		Consequently, the majority of the resultant force produced by the biceps brachii in frame B is now directed toward moving the lower arm segment at the elbow joint; a smaller portion is focused on stabilizing the joint.
		The closer the resultant angle of muscle insertion is to 90 degrees, the larger the angular vector for moving a bony segment, and conversely the smaller the stabilizing force vector for improving joint integrity (Kreighbaum and Barthels, 1996).

	Analyzer for resultant force at joint - Patent 4277828
		The resultant force at the joint has heretofore been determined by use of a pedestrian analyzer or by a method which utilizes a transducer inserted in the patient's body and a telemeter installed separately to receive and analyze data from the transducer.
		The analyzer for the resultant force at the joint according to this invention is not expensive because it is obtained simply by attaching the pair of cursors and the pair of potentiometers to an ordinary device for visual observation of X-ray films and connecting the potentiometers to a small computer.
		By the operation of the data processing unit, therefore, the total muscular force "F" exerted by the group of abductors is determined in accordance with Formula (1) and the resultant force "R" exerted on the head of the femur is determined in accordance with Formula (2).

		Machines and structures are usually subjected to lots of forces. When we analyze force systems, we usually are interested in the sum of the forces. The sum of a set of forces is known as the resultant of the force system.

	Net Force
		The strength of this prevailing force would be the difference between the strengths of the two separate forces.
		For example, if one person pushed the book with a force of 20 Newtons toward the left, and the other person pushed the book with a force of 18 Newtons toward the right, then that the net force would be 2 Newtons in size and directed toward the left.
		And forces which are aimed to the left are usually said to be in a negative direction.

		The single force passing through O is equal to the resultant force of the original system, and the couple is equal to the resultant moment of the original system around point O.

		Such a force is called the equilibrant and is equal in magnitude but opposite in direction to the original resultant force acting on the object.
		In the force diagram the object is drawn as a dot and all forces acting on the object are drawn in the correct directions starting from that dot.
		Since the object is stationary, the resultant force acting on the object is zero.
