Question

The "Established Datum" for number 2 and 3 are marked incorrect. Can you please help me with those two. Please refer to the image below.

Workshop Exercise 6.3 - Datum Feature Exercise
The part below has a variety of features that are
labeled as datum features. Assume all are primary
datum features and the datum features of size apply
Y
at RMB.
Next to the datum feature in the table below,
identify if it establishes a point, axis, plane, or some
combination of these datums. Also list the names
W
of translational (x,y,z) and rotational (u,v,w)
degrees of freedom constrained by the datum
feature. See the isometric view to the right for the
labeled degrees of freedom.
