Quizplus · Accepted Answer

Technician A is correct in stating that a low section modulus (SM) frame can provide a better ride, which is desirable in highway tractors for comfort and stability. Technician B is also correct in saying that a combination of low SM and high rail yield strength can achieve a frame that offers a forgiving ride while maintaining high Resisting Bending Moment (RBM), ensuring the frame is both comfortable and durable.
