1. Adjusting the speed of the rotating shaft alters the frequency of rapping. 2. Similar problems arise when applying LDV to rotating shafts , crankshafts for example. 3. The lower-unit housing contained a flexible inner rotating shaft . 4. The rotating shaft creates an electrical signal proportional to the cable's linear extension or velocity. 5. The result was non-rotating shafts , which gave a quieter sound and less friction on moving parts. 6. Like a mammoth grandfather clock, Cloud Catcher houses humming gears and electric generators and rotating shafts . 7. A drive belt, or a rotating shaft would be expensive and have very high friction losses. 8. Commonly, torque sensors or torque transducers use strain gauges applied to a rotating shaft or axle. 9. In the simplest application, clutches connect and disconnect two rotating shafts ( drive shafts or line shafts ). 10. The rotating shaft ran to the " wind bar " located in front of the body of the gunsight.
