A contractor is evaluating two projects for next year. Project A is expected to have revenue of $10 million and direct costs of $8.5 million. Project B is expected to have revenue of $8 million and direct costs of $6.2 million. Overhead allocation for either project would be $1 million. From a gross margin perspective (ignoring overhead), which project is more attractive, and why?

A contractor’s balance sheet shows total debt of $18 million and total equity of $12 million. The company wants to maintain a maximum debt-to-equity ratio of 1.5. How much additional debt can it take on without exceeding this target, assuming equity remains constant?

An aluminum [E = 7,340 ksi] bar is bonded to a steel [E = 30,550 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +476 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.653 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.2318 in.4, find the magnitude of the maximum bending stress in the steel.

An aluminum [E = 14,750 ksi] bar is bonded to a steel [E = 29,550 ksi] bar to form a composite beam as shown. The composite beam is subjected to a bending moment of M = +464 lb-ft about the z axis. If the centroid of the equivalent all-aluminum beam is 0.584 in. above the bottom surface of the beam, and the moment of inertia about the z axis of the equivalent all-aluminum beam is 0.1720 in.4, find the magnitude of the maximum bending stress in the steel.
