Title: 1250 degrees of coefficiency of friction?
Post by: Aloarjr810 on April 10, 2015, 12:29:30 PM

Okay, this is from old article in Bowl Magazine "Shop Talk" by a Jerry Francomano (about 1989 I think) called "Solving your ball reaction problems".

In it he say's:
"Urethane bowling ball cause upwards 1,250 degrees of coefficiency of friction when rolled on a normal lane surface (i.e. with some oil on it) while rubber bowling balls cause only 250 degrees of surface friction and plastic balls approximately 500 degrees."

You can read it in context here:

So what do you think he is referring to with 1250, 500, 250 "degrees" of coefficiency of friction?


According to "Mo" That is a temperature that Jerry refers to and is the "instantaneous temperature at point of impact of the ball with an unoiled lane. "

A guess would be the friction of ball surface touching the lane creates heat. The heat can be measured.

If the measurement is taken with zero oil,  im guessing it can give an idea of how the ball may break down lane oil.

Coefficient of friction describes the amount of friction between two objects.
