Tension: Concept, Definition, Formula, Unit, Properties And Examples!

Tension; Concept, Definition, Formula, Unit And Examples: When two or more bodies are in physical contact with each other, but one of the bodies is in contact with a rope, string or spring, then the force is said to be tension force.

Some Common Doubts To Be Cleared

• Tension is a pulling force and not a pushing force as ropes can’t be pushed effectively. Most of the time during the explanation of the concept, while illustrating the forces acting on an object, people often draw the force of tension going in the wrong direction. 
• Hence, it is important to remember that tension can only pull on an object but not push against it. 

How To Calculate The Force Of Tension? 

The tension of an object is equal to the mass of the object and the gravitational force is added to the product of the mass and acceleration. 

The formula to be represented mathematically is as follows: 

 T = mg + ma

Properties Of Tension Force

The following properties of Tension force are as follows:- 

• Because ropes cannot effectively push, tension acts as a pulling force. 
• Cables and ropes are used to apply forces as they can transfer the force over a given distance. 
• Tension forces can only be felt while pulling an object away. 
• When the rope has little mass, it transfers the force from one end to another very well. 
• To constitute a force, the load supplied to the material should be exerted axially. 

Factors Affecting The Tension Force

• Applied load: The stronger the pulling force exerted at the string’s ends, the greater the tension inside the string. 
• Cross-sectional area: Thicker cables with large-sectional aerea may handle more tension than the thinner ones. 
• Flexibility: More flexible strings create less tension. 
• Length: Longer strings require more tension. 
• Temperature: Higher temperatures can diminish a material’s strength along with the maximum stress it can sustain while falling. 

Uses Of Tension Force

• In the tug of war, tension forces are applied. 
• It is also used for a variety of gym equipment. 
• Tension force is also used to pull automobiles on a busy highway road.
