🔍 Key Concepts

• Sliding-foot (sliding chock) purpose on large turbines or generators and why it must move freely as the machine heats and cools • How thermal expansion of the turbine casing and base affects attached piping and pressure parts • Relationship between restricted movement of the sliding foot and stress or misalignment in connected components

💭 Think About

• Ask yourself: When the turbine or generator casing heats up, what parts need to slide on these bearing surfaces, and what happens if that sliding is blocked? • Which listed problem would most logically result from the unit being unable to expand freely in line with attached systems? • Of the four options, which one is most directly connected to stresses caused by misalignment along the turbine’s centerline rather than local structural damage or corrosion?

✅ Before You Answer

• Verify which choice is tied to thermal expansion and misalignment rather than to static structural deformation or corrosion. • Check which component in the options is rigidly connected to the machine whose foot is supposed to slide. • Eliminate any option that does not depend on free axial movement of the sliding-foot bearing surfaces.
