Dr. Briggs was
given a bad moment or two over an incident during the rubber crisis.
Early in 1945, the very active Senate Special Committee Investigating
the National Defense Program (the Truman Committee) called on him
to explain how a study he made in the bouncing characteristics of
golf balls and baseballs could possibly contribute to the war effort.
The Committee pointed to a paper he had just published, wonderfully
entitled: "Methods for measuring the coefficient of restitution
and the spin of a ball."
Dr. Briggs explained
and the committee subsided. Prodded to conserve rubber, even in
miniscule amounts, the Services of Supply had asked the bureau about
a substitute material being used in the baseballs it was supplying
recreation centers at training camps. Extending an investigation
he had made of golf balls in an idle hour before the war, Dr. Briggs
took on the SOS request himself. The work, he reported to the committee,
had been done by a high school boy He had merely made the analyses,
with assistance from Dr. Dryden and Dr. Buckingham on the theoretical
considerations.
In baseballs
with balata cork centers (made official in the major leagues in
1943), the coefficient of restitution or liveliness of the ball,
Dr. Briggs found, was measurably reduced over that of the prewar
rubber-cushioned cork center (official in 1938). The coefficient
was still lower in baseballs with reclaimed rubber centers. "A
hard-hit fly ball with a 1943 center," Dr. Briggs reported,
"might be expected to fall about 30 feet shorter than the prewar
ball hit under the same conditions." It was an important finding,
contributing to the peace of mind not only of the professionals
but of the sluggers in the (military) training camps.
