A rod of length L is pulled with a force F from its one end. The tension at every point on the rod is the same. True or false? Justify your answer.

False. The tension is not the same at every point on the rod.

When you pull the rod with a force F from one end, the tension is highest at the point where the force is applied and decreases along the length toward the other end.

This happens because each section of the rod has to pull the rest of the rod behind it, so the tension varies depending on how much of the rod is “to be pulled” beyond that point.

The tension is maximum at the point where the force is applied and zero at the free end if the other end is free, or it changes depending on how the rod is supported or loaded.

So, tension varies along the rod rather than being the same everywhere.

Hey, I think that’s actually false.

The tension isn’t the same everywhere on the rod. When you pull it from one end, the part near where you’re pulling feels the full force F, but as you move along the rod toward the other end, the tension gets smaller because each part only needs to pull the part beyond it.

So, the tension changes from one end to the other instead of staying the same all along the rod.

No, the tension isn’t the same everywhere.

When you pull the rod from one end, the part right where you’re pulling feels the full force, but as you go toward the other end, the tension gets less because each part only has to pull the part after it.

So tension changes along the rod, it’s not constant.

Actually, the tension isn’t the same all along the rod.

The part where you pull feels the biggest tension because it has to pull the whole rod.

But as you move toward the other end, the tension gets smaller since that part is only pulling a smaller piece of the rod.

So, tension changes from one end to the other.
