The greatest riser height within any flight of stairs should not exceed the smallest by more than 3/8 of an inch
This is a building code issue, and so varies depending on location. For example, the State of New York specifies that the maximum difference in riser height for any flight of stairs is 3/8 inch.
Write off is the difference between total charge and the allowable amount by the insurace. Write off is the difference between total charge and the allowable amount by the insurace.
allowable stress design-2/3rd of yield working stress design is process yield
ultimate stress=Factor of safety*Allowable stress

Permissible stress design (in USA construction more commonly called allowable stress design) is a design philosophy used by civil engineers. The designer ensures that the stresses developed in a structure due to service loads do not exceed the elastic limit.
