Pitch Diameter and Drive Ratio. Pulleys and belts have two uses; to increase or reduce speed or torque, or to transfer power from one shaft to another. If the transfer of power is all you need, then two pulleys of the same diameter will do the trick.
Last night's Republican presidential debate drew an average of 22.9 million viewers for CNN, making it the most watched program in the network's 25-year history, the channel reported Thursday. The ratings were larger than the average NFL broadcast, at 19 million viewers, receives.
The liberal cable news network drew an average of 55,000 viewers in the all-important 25- to 54-year-old demo on Tuesday, its lowest full-day rating since July 2005, according to Nielsen ratings provided by an industry source. CNN had nearly three times as many viewers in the demo, Fox News nearly five times as many. That low reflects a more general decline in recent years. In January, MSNBC's daytime ratings for January were down 20 percent in total and 37 percent in the demo when compared to the previous year. In prime time, total viewership was down 23 percent, while the demo dropped by 39 percent.
