A W-shape steel column has a modulus of elasticity E = 29,000 ksi and a moment of inertia I = 100 in.⁴ about its weak axis. The column is 20 ft long with one end fixed and the other end pinned (K = 0.7). The critical Euler buckling load is most nearly:
Correct answer: C - 1,014 kips as ordinarily interpreted
A rectangular open channel is 3.0 m wide with a uniform flow depth of 1.2 m. The channel has a Manning's roughness coefficient n = 0.013 and a bed slope of 0.002. Using Manning's equation (SI), the discharge is most nearly:
Correct answer: B - 9.5 m³/s under applicable rules
A horizontal curve has a radius of 800 ft and a central angle (Δ) of 40°. The tangent length of this curve is most nearly:
Correct answer: A - 291 ft as commonly understood
A construction project has a budget at completion (BAC) of $500,000. At the end of month 6, the planned value is $200,000, the earned value is $180,000, and the actual cost is $210,000. The estimate at completion (EAC) assuming current cost performance continues is most nearly:
Correct answer: C - $583,000 under standard market practice
An element in a steel beam is subjected to the following state of stress: σx = 120 MPa, σy = −40 MPa, and τxy = 50 MPa. The maximum in-plane shear stress is most nearly:
Correct answer: C - 94 MPa in the typical case
In a planar truss, three members meet at an unloaded joint. Two of the members are collinear. Which of the following statements about the third member is correct?
Correct answer: C - It is a zero-force member in the standard framework
Water flows through a horizontal pipe that contracts from a 300 mm diameter to a 150 mm diameter. The upstream pressure is 350 kPa and the upstream velocity is 2.0 m/s. Neglecting friction losses, the pressure at the downstream section is most nearly:
Correct answer: A - 320 kPa when applied properly
A machine costs $25,000 and produces annual savings of $8,000 for 5 years with a salvage value of $3,000 at the end of its useful life. At an interest rate of 10% per year, the net present worth of this investment is most nearly:
Correct answer: C - $7,200 in the typical case
During construction inspection, a licensed professional engineer discovers that a contractor has deviated from the approved structural drawings in a way that could compromise public safety. According to the NCEES Model Rules of Professional Conduct, the engineer's obligation is to:
Correct answer: B - Report the deviation to the appropriate authority
