A beam is part of the framing system for the floor of an office building. The floor is subjected to both dead loads and live loads. The maximum moment caused by the service dead load is 53 ft-kips, and the maximum moment for the service live load is 61 ft-kips (these moments occur at the same location on the beam and can therefore be combined). If LRFD is used, what is the required nominal strength of the beam for a resistance factor φ of 0.90?

A tensile test was performed on a specimen having a circular cross section with a diameter of 0.625 inch. The gage length (the length over which the elongation is measured) is 2.0 inches. For a load of 14.0 kips, the elongation was 0.00606 inches. If the load is assumed to be within the linear elastic range of the material, determine the modulus of elasticity.

A flat roof is subject to the following uniformly distributed loads: a dead load of 30 psf (pounds per square foot of roof surface), a roof live load of 13 psf, a snow load of 12 psf, and a wind load of 26 psf downward. If LRFD is used, what is the required nominal strength of the member for a resistance factor φ of 0.70?

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 1.140 inch. Two marks were made along the length of the specimen and were measured to be 2.250 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 23,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.703 inch and 2.535 inches. Determine the elongation as a percentage.
