A 3/8 in. x 11 in. plate must resist a service dead load of 58 kips and a service live load of 54 kips in tension. The plate is connected to a gusset with eight 1 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A36: Fy = 36 ksi, Fu = 58 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 1.050 inch. Two marks were made along the length of the specimen and were measured to be 2.900 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 26,000 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.599 inch and 3.212 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 10 psf, a snow load of 17 psf, and a wind load of 27 psf downward. If LRFD is used, determine the factored load (required strength), Ru.

A 5/8 in. x 5 in. plate must resist a service dead load of 24 kips and a service live load of 30 kips in tension. The plate is connected to a gusset with three 3/4 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 42: Fy = 42 ksi, Fu = 60 ksi. Assume that Ae = An. Using LRFD, does the plate have enough strength?
