what is tension in physics?

Question

especially when a rope is pulled and when load is placed on a rope which is tied at two ends

Answer 1

Tension is a force. It is an external stress tending to pull and object apart. If the force of tension is greater than the inward force of the object, then the object will stretch. Many objects, such as ropes and cables, can only be loaded with tension. If these objects are compressed, then they deform.

Answer 2

Tension is a force acting opposite and equal to each other between two fixed points and keeps the rope or string straight. When a load is placed on the straight rope tied at both ends, the tension of the rope will increase and makes the rope slightly bent at the point of load acting. Instead of a single line , now the rope appears to have two straight line as if the rope is tied at the point of application of load and the two end points.

Answer 3

Going back to the basics, Newton's 3rd Law says "For every action there is equal and opposite reaction". Tension in the internal force which is exerted by a system internally as a reaction to external force applied on it.
For eg. if a rope hanging from a support is carrying a mass 'm' on its free end, the downward force on the rope will be "mg" (where g is the gravitational force). The tension (internal force) acting in vertically upward direction will be equal to downward force "mg". This is how the system is maintained in equilibrium.
When the rope is tied at both the ends and loaded at the center, the equal tension in the rope acts towards both the ends. In this case it is not equal to downward pull because there is only a resultant (partial) force acting as tension towards both the ends. This can be calculated using simple vector analysis and trigonometry.
Hope this helps.

Answer 4

Tension is a reaction force applied by a stretched string (rope or a similar object) on the objects which stretch it. The direction of the force of tension is parallel to the string, towards the string.

Tension exists also inside the string itself: if the string is considered to be composed of two parts, tension is the force which the two parts of the string apply on each other. The amount of tension in the string determines whether it will break, as well as its vibrational properties, which are used in musical instruments.

The magnitude of the force of tension typically increases with the amount of stretching. For small stretching, the force is often described by Hooke's law.

String-like objects in relativistic theories, such as the strings used in some models of interactions between quarks, or those used in the modern string theory, also possess tension. These strings are analyzed in terms of their world sheet, and the energy is then typically proportional to the length of the string. As a result, the tension in such strings is independent of the amount of stretching.

Answer 6

The tension is the pressure on the Rope which the rope can Handle or Not.

Answer 7

Hi. It is a measure of force being withheld by the medium, rope or not. For instance, surface tension in a liquid it a force of attraction between the molecules of that liquid.

Answer 8

Ah stress, a stressful subject remember through fact no physics instructor can teach it good. ok, so what you have is a equipment of plenty and that they are all pulled collectively so as that they could all have an identical acceleration, it is the 1st significant component. So a(internet) = F(internet)/m(internet) = 10/7 = a million.43m/s/s. Now, we could say you have lower back truck -> front truck -> youngster there is largely one rigidity performing horizontally on the lower back truck, and that's the stress rigidity (different than for friction needless to say). Now through fact it somewhat is the only rigidity we are able to apply F=ma to calculate the stress. We basically use the mass of the 2d truck through fact we would desire to be attentive to the rigidity basically appearing on it, no longer the equipment of the vehicles. F(stress) = 2*a million.40 3 = 2.86N outstanding question. I bear in techniques having super situation with this thought myself, yet sometime it only clicked, optimistically that day will come to you quickly. i'm hoping i've got helped you, i've got tried my ultimate.

Answer 9

The condition of a string, wire, or rod that is stretched between two points.

The force exerted by the stretched object on a support.

Answer 10

force which supports the system, is along the string and acts away from the system.
