The enzyme Pepsin works best in a/an __________________ environment 

_______ are vertical members primarily subjected to axial compression.

The nurse is caring for a client with atrial fibrillation. What manifestation most alerts the nurse to the possibility of a serious complication from this condition? 

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.

In ASD, allowable strength = nominal strength / _______.

A column is loaded in compression as follows. What is the controlling factored load for LRFD?Dead load: 17 kipsFloor live load: 2 kipsRoof rain load: 9 kipsRoof live load: 6 kips

When connecting a tension member with bolts, the reduced area (area with the holes removed) is called _______, and the unreduced area (area without holes) is called _______.

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.

The _______ strength must exceed the _______ strength.
