Torque
Torque is experienced in simple day to day activities such as turning a doorknob, fastening a bolt, turning the steering wheel, paddling a bicycle, or even turning your head. It must be noticed that in each and every one of these activities, the movements are circular or rotational movements. It can be shown that in every movement where a change in the angular momentum occurs, there is always a torque acting upon the object. A torque is generated by a pair of forces, similar in magnitude and opposite in direction and parallel to each other. These two forces are separated by a finite distance. In physics, the term moment also has the same meaning as torque. Torque is defined as the tendency of a force to rotate an object about an axis, a fulcrum or a pivot. A torque can also be provided using a single force acting at a distance r from the axis of rotation. The torque of such a system is equal to the cross product of the applied force and r. Torque is mathematically defined as the rate of change of angular momentum of and object. It can be clearly seen that this is compatible with the force - linear momentum relationship in linear movements. The torque is also equal to the product of the moment of inertia and the angular acceleration. Torque is a vector with the direction determined by the cross product of the force and distance. It is perpendicular to the plane of rotation.
Torsion
Torsion is experienced in day to day activities such as tightening a screw or twisting a cloth. Torsion is the deformation of objects due to a pair of equal and opposite torques. There can be torsion even if the net torque of the system is zero. If a single torque is applied to a fixed object, which cannot rotate in any direction freely there will always be another torque generated by the reactive forces on the fixed point. The amount of twisting due to an applied torque depends on the torsional rigidity of the system. The twist angle and the torque hold a linear relationship, where the torsional rigidity is the proportionality constant.
What is the difference between torque and torsion?
- Torque is a measureable concept, whereas torsion is a concept, which is mathematically projected by the shear stress or the twist angle.
- Torque requires at least one force and torsion requires at least two forces to happen.
- Torque depends only on the magnitude, directions and the separation of the forces applied, while torsion depends on the torque, the type of material and the shape of the object.

Which oscillations are seen in torsion pendulum?
In a torsion pendulum, torsional oscillations are observed. These oscillations involve the twisting of a wire or shaft that suspends the pendulum mass, resulting in a rotational motion back and forth. The restoring force for these oscillations comes from the torsional stiffness of the wire or shaft.
What is the difference between a 350 Chevy crank shaft and a 400 crank shaft?
400 has a longer stroke
What is torque in a graphite golf shaft?
Torgue refers to the twisting that happens to the shaft of a club as it is swung. Not only does the shaft of a golf club flex or bend as it is swung but it twists also. A graphite shaft manufacurer that markets a shaft as having low torque for examle, is saying that the shaft is designed to resist twisting as it is swung. The theory being less torque creates a more stable clubhead at impact.

What is distance difference between a graphite 7 iron and a steel shaft 7 iron?
I graphite shaft compared to a steel shaft on any club will give you more distance. For every club there will be roughly a five yard distance difference. You will hit the graphite further.
What is the torsional rigidity of a shaft?
Torsional rigidity of a shaft, also known as torsional stiffness, refers to the shaft's resistance to twisting under an applied torque. It is a measure of how much the shaft twists relative to the applied torque. Torsional rigidity is important in applications where precise torque transmission is required without excessive twisting or deformation of the shaft.
What is the difference between hole basis system and shaft basis system?
In a hole basis system, the dimensions of the hole are kept constant while the dimensions of the shaft are varied. In a shaft basis system, the dimensions of the shaft are kept constant while the dimensions of the hole are varied. The choice between the two systems depends on the specific application and the importance of the fit between the shaft and hole.
What is the difference between a taylormade reax 55 shaft and a reax 55 soft tip graphite shaft?
The Taylormade REAX 55 shaft is a made by Mitsubishi Rayon. The graphite shaft is more brittle and therefore more prone to damage. However, there should be no distinquishable difference in the playing characterics beween the two shafts.
