The main engine flexible coupling serves to protect the engine from which type of forces?

• A. Longitudinal and angular forces
• B. Radial and lateral forces
• C. Vertical and torque forces
• D. Shear and compressive forces

Answer: (A)

The main engine flexible coupling is designed to accommodate and mitigate longitudinal and angular forces that can arise during engine operation. Longitudinal forces are those that act along the shaft's length, while angular forces are related to misalignment or changes in angle between the connected components. The flexible coupling allows for some degree of movement and flexibility in these directions, ensuring that vibrations and mechanical stresses do not adversely affect the engine or connected equipment. By absorbing these forces, the coupling helps to maintain alignment and reduce wear on both the engine and the transmission systems, contributing to the overall reliability and longevity of the machinery.
