Question

How are tensional forces created?

Answer 1

Tensional forces are created when a perpendicular force is applied to a flexible connector. The larger the force applied, the greater the tension. This is exemplified by a tightrope walker whose weight and additional acceleration create tension in the rope.

Step-by-step explanation:

Tensional forces are created when a force is applied perpendicular to a flexible connector, such as a rope or cable. This is commonly observed when a tightrope walker walks across a rope, with their weight providing the perpendicular force that creates tension in the rope.

The tension in the rope can be considered as a reaction force to the applied force, which in the case of the tightrope walker, includes both the gravitational force (the walker's weight) and any additional force due to the walker's acceleration (F = ma).

If a larger tension is desired, one would need to apply a greater perpendicular force to the connector. The greater the force applied, the greater the tension that is created. This is a fundamental concept in applications ranging from engineering structures to performances in a circus.

An extended expression that describes the tension (T) is when a perpendicular force (F1) is exerted at the middle of a flexible connector. The rope must support not only the weight of the tightrope walker but any additional forces from movement, essentially the force of gravity (mg) plus the force necessary to accelerate the mass (ma).

Answer 2

Tensional forces are created on a piece of string or rope or anything similar when it is pulled tight from both sides, that is, when forces are acting on both ends, thus tightening it. The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.
