question 69 of 100 · multiple choice

using the rim and face alignment method, the rim reading indicates?

a soft foot

b offset

c bar sag

d angularity

Explanation:

Identify the measurement target of rim readings

The rim dial indicator measures the radial distance between the outer diameters of the two coupling halves as they rotate, which directly corresponds to the radial offset (parallel misalignment) between the shaft centerlines.

Identify the measurement target of face readings

The face dial indicator measures the axial distance between the coupling faces at different angular positions, which corresponds to the angularity (angular misalignment) between the shafts.

Match with the given options

Since the question asks what the rim reading indicates, it corresponds to offset misalignment.

Answer:

• (A) soft foot
• (B) offset (Correct answer)
• (C) bar sag
• (D) angularity
