There is in fact a change in slope - you can see this when you fit a straight line through the data, then subtract it to look at the residuals: It seems that the first three data points lie on a steeper curve than the remainder - as though something changed in the setup (did thing heat up?) Residuals plots are an essential tool when you analyze data that ...

All things being equal, the contribution of a mass element to the total moment of inertia about a given axis increases as the square of its distance from the axis of rotation. Basically, you want to put as much mass as possible as far away from the rotational axis as possible. Since your question appears to imply that the axis of rotation is the center axis ...

Tricky question. Basically you would think the total force is 0 on any plane intersecting the cylinder at right angles, hence there would be no pressure, right? Well, the first point (0 net force) is correct, second is not. Imagine being physically pulled by two equally strong friends in opposite directions. Total force is 0 so you remain standing where you ...
