A 1/2 in. x 8 in. plate must resist a service dead load of 37 kips and a service live load of 44 kips in tension. The plate is connected to a gusset with six 5/8 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 60: Fy = 60 ksi, Fu = 75 ksi. Assume that Ae = An. Using ASD, does the plate have enough strength?

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 0.770 inch. Two marks were made along the length of the specimen and were measured to be 2.350 inches apart. This distance is defined as the gage length, and all length measurements were made between the two marks. The specimen was loaded to failure. Fracture occurred at a load of 20,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.278 inch and 2.625 inches. Determine the reduction in cross-sectional area as a percentage.

A flat roof is subject to the following uniformly distributed loads: a dead load of 25 psf (pounds per square foot of roof surface), a roof live load of 13 psf, a snow load of 16 psf, and a wind load of 27 psf downward. If ASD is used, determine the required load capacity (required strength), Ra.
