Several weeks ago a reader by the name of Anthony Fletcher mentioned the fact that in rowing the oar acts as a lever, with the oarlock acting as the fulcrum of the lever (19TH HOLE, Aug. 9). According to my physics teacher nothing could be further from the truth.
Certainly the oar is a lever. However, the blade is the fulcrum, while the oarlock is the load or resistance. After all, are you moving the boat or the water? Technically this is known as a second-class lever, the resistance being between the effort and the fulcrum.
DAVID CHARLES ZALK
?Correct. In a practice tank the oarlock serves as a fulcrum, but when a shell is afloat the point at which the blade of the oar bites the water becomes the fulcrum and the load is centered on the oarlock. In simplest terms, if the oar is 12 feet long and the oarlock is located nine feet from the tip, a 200-pound rower need exert—in theory, at least, and discounting such realities as friction and the weight of the oar—only 150 pounds of effort to pull his weight. If the oarlock were the fulcrum, the effort required to move 200 pounds would be 600 pounds.—ED.
LISTEN, THE WIND
Congratulations on Myron Cope's story about Bob Prince (The Prince of Pittsburgh, Sept. 13). It takes a great writer to write about a great sportscaster, toastmaster, television celebrity and humanitarian of the caliber of Bob Prince. You do not have to like a person in this world to respect him, and this is why Prince is kidded so much. When Pittsburghers stop talking about Prince and quit believing that "the wind is a factor," Prince will have quit broadcasting for at least five years.

An ideal trade would be the "Prince of the Pirates" for Kansas City's mule.
The way to enjoy a Pirate game when the "Prince of the Pirates" is rambling on TV is to turn off the sound and listen to Don Hoak and Jim Woods via transistor radio.

A. K. (Rosey) Rowswell, Prince's predecessor and the fellow you refer to as a shriveled old man, was probably one of the great baseball announcers of all time. To be sure, his technical description of the game may not have been outstanding, but he did convey a sense of a true love of baseball and humanity. In the tri-state area he was that rare radio personality whom you regarded as a friend even though you had never met him. I think Bob Prince is a fair baseball announcer, but there are few human beings who were ever in the same league with Rosey Rowswell.

You say Prince thinks he is the manager and he is always wrong. You didn't mention the game with the Braves on May 22. He said Willie Stargell would hit a home run, and Stargell did. He said Clendenon would hit one, and Donn did. He said Mazeroski would hit a soft single, and Bill did. He called all the plays right that day.

Shame on the Pittsburgh fans who boo the most entertaining guy connected with the Pirates. Baseball has become so dull and the players so colorless that only a Prince can create an interesting picture. The average fan is less likely to remember pitching records and batting averages than the zany antics of the greatest players. Sportscaster Bob Prince makes baseball come alive over the air and, to paraphrase his favorite line, he's had me all the way.
