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 52 ft-kips, and the maximum moment for the service live load is 75 ft-kips (these moments occur at the same location on the beam and can therefore be combined). If LRFD is used, determine the maximum factored bending moment (required moment strength), Ru.

A 3/8 in. x 5.0 in. plate is connected to a gusset with four 5/8 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A1066 Grade 50: Fy = 50 ksi, Fu = 65 ksi. Assume that Ae = An. Compute the design strength for LRFD.

A tensile test was performed on a specimen having a circular cross section with a diameter of 0.250 inch. The gage length (the length over which the elongation is measured) is 1.0 inches. For a load of 8.0 kips, the elongation was 0.00655 inches. If the load is assumed to be within the linear elastic range of the material, determine the modulus of elasticity.

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