A tensile test was performed on a specimen having a circular cross section with a diameter of 0.500 inch. The gage length (the length over which the elongation is measured) is 1.5 inches. For a load of 15.0 kips, the elongation was 0.00805 inches. If the load is assumed to be within the linear elastic range of the material, determine the modulus of elasticity.

A 3/4 in. x 8 in. plate must resist a service dead load of 32 kips and a service live load of 52 kips in tension. The plate is connected to a gusset with six 1-1/8 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 ASD, does the plate have enough strength?
