Metalworking The surface speed S in fpm (feet per minute) of a rotating cylindrical object is
where d is the diameter of the object in inches and n is the speed of rotation in rpm (revolutions per minute). If an 8-in. grinder must have a surface speed of 6000 fpm, what should the speed of rotation be? Use
