Tension In Rope: Box Suspended & Pulled by Force

In summary, a box suspended by a rope experiences an increase in tension when pulled by a horizontal force due to Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. This results in an equal reaction being exerted on the rope, leading to an increase in tension. To understand this concept, one can solve force balance equations and expand them in a coordinate frame if needed.

A box suspended by a rope is pulled to one side by a horizontal force. The tension in the rope increases! Why is it so?

Have you solved the force balance equations, as zwierz suggests, and found that the tension increases, or were you told that it increases and you're trying to understand why?

Because for every action if force there is an equal and opposite reaction. Thus this equal reaction must get exerted upon the rope, as it is supporting the object on which the force was exerted. Ergo...more tension on the rope.
 

Related to Tension In Rope: Box Suspended & Pulled by Force

1. What is tension in a rope?

Tension in a rope is a force that is exerted on the rope when it is pulled or stretched. It is the measure of the amount of force that is being applied to the rope.

2. How is tension affected by the weight of an object?

The weight of an object has a direct effect on the amount of tension in the rope. The heavier the object, the more tension will be exerted on the rope.

3. Why does tension increase when an object is suspended in a box?

When an object is suspended in a box, the weight of the object is distributed evenly throughout the box. This causes the tension in the rope to increase as the weight is being supported by multiple points rather than just one.

4. How does the angle of the rope affect the tension?

The angle of the rope has a significant impact on the tension. The greater the angle, the greater the tension will be. This is because a larger angle means the force is being distributed over a larger area, resulting in a greater tension being exerted on the rope.

5. Does the type of rope used affect the tension?

Yes, the type of rope used can affect the tension. Different types of rope have different properties and can stretch or break at different levels of tension. It is important to use a rope that is suitable for the amount of tension being applied to prevent any accidents or damage.
