Typical Load Combinations For Residential Buildings
Attic loads may be included in the floor live load but a 10 psf attic load is typically used only to size ceiling joists adequately for access purposes However if the attic is intended for storage the attic live load or some portion should also be considered for the design of other elements in the load path.

Comparison of grinding kinetics between a typical ball
A ball mill with a breaker plate and a similarly sized typical ball mill without a breaker plate were studied in order to determine if the breaker plate can improve mill grinding efficiency At hypocritical frequencies of rotation it was found that the ball mill with the breaker plate grinds more efficiently and especially so for particles larger than 1 mm The breakage function for the ball
