A column in a building is subjected to the following load effects. If LRFD is used, what is the value of required strength, Ru?8 kips compression from dead load4 kips compression from roof live load9 kips compression from snow5 kips compression from wind

A 3/8 in. x 10 in. plate must resist a service dead load of 41 kips and a service live load of 52 kips in tension. The plate is connected to a gusset with six 1-1/2 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. Using LRFD, does the plate have enough strength?

A tension member must be designed for a service dead load of 50 kips and a service live load of 2 kips. If LRFD is used, determine the maximum factored load (required strength), Ru.

A 0.99 in. x 10.7 in. plate is connected to a gusset with eight 1-1/8 in. bolts. Standard sizing is used for the bolt holes. What is the net area of the plate?

A 3/8 in. x 11.0 in. plate is connected to a gusset with eight 7/8 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 60: Fy = 60 ksi, Fu = 75 ksi. Assume that Ae = An. Compute the allowable strength for ASD.

A 3/4 in. x 12.0 in. plate is connected to a gusset with eight 1/2 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.

____________________ electrification occurs when a conductor connects two objects with different charges.

A 1/2 in. x 6.0 in. plate is connected to a gusset with four 1-1/4 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 allowable strength for ASD.

Conductors are commonly made from copper, aluminum, and ___.

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 0.790 inch. Two marks were made along the length of the specimen and were measured to be 2.650 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 24,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.388 inch and 2.941 inches. Determine the reduction in cross-sectional area as a percentage.
