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.

You are making a home visit to a client receiving external radiation therapy. Which of the following observations would indicate a need for further teaching? 

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?

A 0.64 in. x 4.1 in. plate is connected to a gusset with three 1-1/4 in. bolts. Standard sizing is used for the bolt holes. What is the gross area of the plate?

When teaching a client with heart failure about preventing complications and future hospitalizations.  Which problems, stated by the client as reasons to call the physician would indicate to the nurse that the client has understood the teaching (Select all that apply)?  

Significant figures are important because too few can imply an unrealistic degree of precision but too many can lead to meaningless results.

What is the effective hole diameter to accommodate a 1 in. bolt? Use oversize hole sizing.

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 0.960 inch. Two marks were made along the length of the specimen and were measured to be 2.000 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 15,000 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.526 inch and 2.211 inches. Determine the ultimate tensile stress.

A nurse is teaching a client who has COPD about ways to facilitate eating.  which of the following statements indicates a need for further teaching?
