Difference between torque and torsion

-
Torque and torsion are key concepts often encountered by students studying mechanics. These terms also confused students most often because of the similarity between them. There are some similarities between torque and torsion but there are noticeable differences too. The difference between them will be explained in this article. Let us check out points on the difference between torque and torsion discussed below. 

What is Torque?

The twisting force that causes motion is known as torque refers to the turning effect. The point of the rotation of the object is called the axis of rotation. The concept of torque originated with the studies by Archimedes when ideas of the usage of the levers.

What is Torsion?

The action of twisting or the state of being a twist of the one end of an object related to another end. The torsion is the twisting of an object due to an applied torque. 

Points on the difference between torque and torsion:

  • Torque is twisting force we apply to perform the action while torsion defines the state of being twisted having one end keeping fixed.  
  • Torque is a measurable concept, whereas torsion is a concept, which is mathematically projected by the shear stress or the twist angle. 
  • Torque requires at least one force on the other hand torsion that requires at least two forces. 
  • Torque depends only on the magnitude, directions and the separation of the forces applied, while torsion depends on the torque and the type of material and the shape of the object. 
  • Torque has the ability to create an angular acceleration and torsion is a twist produced due to torsion.

Difference between characteristic and universal gas constant

-
Some important point on the difference between characteristics gas constant and universal gas constant are explained below. Let us check out one by one below. You can also check out characteristics equation of gas , and general gas equation to know more about it. Difference between characteristics gas constant and universal gas constant: Constant gas characteristics vary from gas to gas but the constant of universal gas is fixed. If you working at human scales, then use universal gas constant, whereas if you want to gas constant that defined per unit mass of a specific gas, then use the specific gas constant.  The characteristic gas constant in equation P = RT is the value of R for a given gas for use. It is equal to the constant of universal gas divided by the molar mass of the particular gas. Characteristics gas Constant applicable for an ideal gas, whereas universal gas constant applicable for a real gas.  Units: Characteristics gas constant - k J / kg K and Univers

Varignon's principle of moments | Varignon's Theorem

Varignon's theorem also called the principle of moments.  Varignon's Principle: Varignon's principle states that if a number of concurrent forces acting on a particle are in equilibrium, then the algebraic sum the moments that each force creates about a single point will be equal to the moment of their resultant force about the same point.   Varignon's Theorem From the above figure, F1 and F2 are two concurrent forces and their resultant is R. The moment produced by R with respect to a moment center O is R × d. The moment produced by the force F1 and F2 is respectively F1 × d1 and F2 × d2.  As per varignon's therorem R d = F1 d1 + F2 d2 Notes: This theorem initially stated for two concurrent forces, but, it is true for any system of forces and any number of concurrent or coplanar forces.  One of the practical applications of this theorem is to find the unknown reactions when a system is known to be in equilibrium under the acti

Difference between moment and couple

-
Moment and couple are two important concepts found in mechanics. They both terms describe the effect and cause of rotation in the system of forces , particle systems, and rigid bodies too.  What is a moment of a force? The turning effect produced by a force applied to a rotational system or on the body at a distance from the axis of rotation is called the moment of force . The moment of a force is the product of the force and the perpendicular distance of the point, about which the moment is required and the line of action of the force. What is a couple OR moment of a couple?   In mechanics, a couple refers to two equal and opposite forces, whose line of action is different from a couple . The couple also called a force couple or pure moment.  Points of difference between moment and couple are discussed below. So let us check out some key differences between them to know more about it.  Difference between moment and couple: The moment is the
