A 5/8 in. x 4.0 in. plate is connected to a gusset with three 3/4 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM 1066 Grade 50: Fy = 50 ksi, Fu = 65 ksi. Assume that Ae = An. Compute the allowable strength for ASD.

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 0.810 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 18,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.399 inch and 3.123 inches. Determine the ultimate tensile stress.
