Tension in a string is the force that is transmitted through the string when it is pulled at both ends. It is the measure of how much the string is stretched or compressed.
The tension in a string can be calculated using the equation T = F/A, where T is the tension, F is the applied force, and A is the cross-sectional area of the string.
When force is applied to both ends of a string, the tension in the string increases. This is because the force causes the string to stretch, and the tension is the reaction force that resists this stretching.
The tension in a string is affected by the material properties of the string, such as its elasticity and strength. It is also influenced by the magnitude and direction of the applied force, as well as the length and thickness of the string.
The tension in a string is directly proportional to the speed of a wave traveling through it. This means that as tension increases, the speed of the wave also increases. This relationship is described by the equation v = √(T/μ), where v is the speed of the wave, T is the tension, and μ is the linear density of the string.
