What statement is true concerning the arrangement of line shaft bearing housings?

ALine shaft bearing housings are typically split half pedestal type bearing housings.

BLine shaft bearing housings are typically split half flange type bearing housings.

CLine shaft bearing housings are typically single-piece flange type bearing housings.

DLine shaft bearing housings are typically single-piece pedestal type bearing housings.

AI Explanation

The correct answer is A) Line shaft bearing housings are typically split half pedestal type bearing housings. This is because split half pedestal type bearing housings are the most common arrangement for line shaft bearings. This design allows the bearing to be easily installed and removed by separating the two halves of the housing, which facilitates maintenance and inspection of the shaft and bearings. The other answer choices are incorrect because split half flange type (B), single-piece flange type (C), and single-piece pedestal type (D) bearing housings are less commonly used for marine line shafts compared to the split half pedestal design.
