The torsion meter for the main propeller shaft is reading high. The torque is sensed using the angle of twist principle with two clamp rings attached to the shaft at a fixed distance, with stationary proximity switches for measuring the angle of twist and also shaft speed fixed to a rigid stool. What is the most likely cause of the high reading?

Ответ: Circumferential slip of the after clamp ring in the opposite direction to shaft rotation.

• Axial slip of one of the clamp rings to move them further apart.
• Circumferential slip of the after clamp ring in the opposite direction to shaft rotation.
• Axial slip of one of the clamp rings to bring them closer together.
• Circumferential slip of the forward clamp ring in the opposite direction to shaft rotation.
