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.

A tension member must be designed for a service dead load of 45 kips and a service live load of 5 kips. If ASD is used, determine the maximum load (required strength), Ra.

What is the effective hole diameter to accommodate a 1-1/2 in. bolt? Use standard hole sizing.

A column in a building is subjected to the following load effects. If ASD is used, what is the value of required strength, Ra?10 kips compression from dead load2 kips compression from roof live load4 kips compression from snow4 kips compression from wind

For ASD, the safety factor for fracture is larger than the safety factor for yielding.

A 1.15 in. x 11.2 in. plate is connected to a gusset with eight 1 in. bolts. Standard sizing is used for the bolt holes. What is the gross area of the plate?

A 0.54 in. x 9.3 in. plate is connected to a gusset with six 1-1/4 in. bolts. Standard sizing is used for the bolt holes. What is the net area of the plate?
