A. Live loads can be reduced when a structural member supports more than 150 square feet in the occupnacy is not public assembly and if the live load is less than 80 psf. B. Live loads include snow, people, and furniture. C. Any live load reduction cannot exceed 40 percent for structural members supporting load form one story. D. Snow load reduction is calculated according to the formula Rs= S/40 - 0.5 if the roof pitch is more than 20 degrees Click here for answer The elastic limit of a material is: A. the point at which a material continues to deform without any increase in load B. the maximum unit stress that determines the engineering working stress to design a member C. the point beyond which unit stress increases faster than unit strain. D. the unit stress below which deformation is directly proportional to stress..
