Tearing Toilet Paper

If an item has a larger mass, then it's rotational inertia will be larger. Hence, it will be harder to make a full(heavier) roll to spin by pulling it, so it will be easier to tear the piece of paper off.

The torque exerted on roll A is greater which would cause the roll to angularly accelerate rather than allow for paper to be torn off. The rotational inertia of roll A is also greater, which would tend to keep the roll from angularly accelerating. However, torque is proportional to radius and rotational inertia is proportional to the square of the radius. So the increase in rotational inertia is the more significant effect, making it easier to rip paper from roll A. This is easy to demonstrate with actual rolls of toilet paper. (Roll A also has a higher mass which increases it's rotational inertia even more.)

Well, its about inertia, as its more when the roll is full

Just took a poo so many times this week that this was easy to remember

It has to do with torque, but common sense says the heavier one requires less force to create a turning effect since it's own weight has generated most.

Points for A (in basic terms)

More Mass more inertia +1 )( Greater radius greater torque -1 )(Kevin disclaimed the torque though so +1

I would add that friction in a real situation could also be a big factor but again this would support the heavier roll +1 Points for A=2

Finally, my habbit's being useful. I gone through a lot of toilet paper rolls and I did that all the time, according to my observation, bigger roll is heavier so it takes more force to get it rolling, so it has more resistance.

A. Here is why: If an item has a larger mass, then it's rotational inertia will be larger. Hence, it will be harder to make a full(heavier) roll to spin by pulling it, so it will be easier to tear the piece of paper off.

Should include a choice for no difference for completeness. It is Roll A because it has more rotational inertia both from being more massive and having a greater radius.

The larger roll has more mass and will offer more resistance to movement for 2 reasons. Inertia and friction against the wall. The resistance to movement makes it more likely to tear than just unroll.

But why can’t you use two hands? But if this person had whatever case to use one hand answer ,A’ would’ve been better because if the roll is bigger the smallness of a piece is bigger than by a small roll, so for example if you take the same length of toilet paper it will seem bigger in the larger roll, and smaller in the smaller roll.

I just thought about a moment (force times a distance) and imagined a free body diagram. The larger roll had a longer distance from the tube, so it required less (downward) force compared to the smaller roll when trying to accomplish the same result.
