HOPE THAT THIS HELPS YOU.

Answer 2

Answer:

B) < (1.75/2)

Explanation:

According to the American Concrete Institute Committee 336 (1988), mats should be designed by the conventional rigid method if the spacing of columns in a strip is less than 1.75/β. If the spacing of columns is larger than 1.75/β the approximate flexible method may be used.
