The _______ factors account for uncertainties in material properties, design theory, and fabrication and construction practices.

Is structural steel considered a ductile or brittle material?

A 0.93 in. x 4.6 in. plate is connected to a gusset with three 7/8 in. bolts. Standard sizing is used for the bolt holes. What is the gross area of the plate?

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 0.880 inch. Two marks were made along the length of the specimen and were measured to be 2.500 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 17,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.406 inch and 2.684 inches. Determine the ultimate tensile stress.

A 5/8 in. x 9.0 in. plate is connected to a gusset with six 1-1/8 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. Compute the design strength for LRFD.

A nurse is caring for a client receiving nasogastric suctioning.  Which of the following ABG values does the nurse anticipate?

A home health nurse visits a client who has COPD and receives oxygen at 2 L/min via nasal cannula.  The client reports difficulty breathing.  Which of the following actions is the nurse’s priority?

A nurse in the emergency department is caring for a client who has a 30% burn injury to her lower extremities.  Which of the following interventions should the nurse perform first?

A column is loaded in compression as follows. What is the controlling factored load for ASD?Dead load: 20 kipsFloor live load: 6 kipsRoof rain load: 8 kipsRoof live load: 9 kips

Dead loads do not include the weight of the structure itself.
