70% to passWhat statement is true concerning the illustrated boiler saddle, support and foot? Illustration SG-0015
AThe illustrated foot is the sliding foot located underneath the front of the water drum.
BThe illustrated foot is the sliding foot located underneath the rear of the water drum.
CThe illustrated foot is the fixed foot located underneath the front of the water drum.
DThe illustrated foot is the fixed foot located underneath the rear of the water drum.
AI Explanation
The correct answer is A) The illustrated foot is the sliding foot located underneath the front of the water drum. The sliding foot located underneath the front of the water drum allows the boiler to expand and contract as it heats up and cools down, preventing stress on the boiler structure. This is the proper design to accommodate the thermal expansion of the boiler. The other options are incorrect because the foot is not located underneath the rear of the water drum (B and D), and it is a sliding foot, not a fixed foot (C).
