Tension, in its various contexts, is affected by a multitude of factors. We'll explore the key influences depending on the type of tension being considered.
Tension in Physical Systems (Strings, Cables, etc.)
The tension in a string or cable is primarily determined by the applied load or pulling force. The stronger the pull at the ends, the higher the tension within the material. Other contributing factors include:
- Material Properties: The material's elasticity and strength directly impact its ability to withstand tension. A stronger, less elastic material will experience higher tension under the same load.
- Length: Longer strings or cables generally exhibit a greater degree of tension under the same load compared to shorter ones.
- Gauge/Thickness: Thicker strings or cables can handle more tension before breaking. Thinner ones will reach their breaking point at lower tension levels.
- Break Angle: In systems like guitars, the angle at which the string contacts the bridge and other components influences the amount of tension. A steeper angle increases tension.
Example: A guitar string's tension is adjusted by tuning pegs. Tightening the pegs increases tension, resulting in a higher pitch. The string's gauge, scale length, and bridge height also affect its tension. This is explained in the provided Reddit thread discussing guitar bridge height and its impact on string tension. https://www.reddit.com/r/AskEngineers/comments/14wk4vx/effect_of_guitar_bridge_height_on_string_tension/
Surface Tension
Surface tension, a property of liquids, is affected by:
- Temperature: Generally, surface tension decreases as temperature increases.
- Chemicals: The addition of certain chemicals (surfactants) can significantly reduce surface tension.
- Concentration: The concentration of dissolved substances can alter surface tension.

Psychological Stress (Mental Tension)
Many factors can contribute to psychological stress, including major life events like the death of a loved one, financial problems, or relationship difficulties. Minor stressors can also accumulate over time, leading to significant stress. References mentioning this include:

The impact of psychological stress on the body is substantial and can manifest in various physical and behavioral symptoms.
