Uniformly distributed around the circumference Loads (Statics and Mec)

[Willjeezy]

Homework Statement

My question is this, they say that at point B the 30kN force is uniformly distributed

If a force is uniformly distributed shouldn't the units be 30kN/mIf so, wouldn't that imply the point force would act in the center of the disk and the force would be be 30kN multiplied by the area of that disc?

How come in the FBD they just drew it as 30kN? Hoping someone can clear this up for me.

The total load is 30 kN. You don't know the exact circumference of the circular plate, so 30 kN/m would not mean anything useful.

IMO, they are saying the load is distributed evenly around the circumference of the circular plate to suggest there are no eccentric axial loads placed on the shafts.
