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 13 psf, a snow load of 16 psf, and a wind load of 27 psf downward. If ASD is used, determine the required load capacity (required strength), Ra.

A column in a building is subjected to the following load effects. If LRFD is used, what is the required nominal strength of the column for a resistance factor φ of 0.55?12 kips compression from dead load7 kips compression from roof live load9 kips compression from snow9 kips compression from wind

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.
