4.30. The phasor diagram for a 60-Hz, three-phase synchronous generator is shown in Fig. P4.30. Note that all sides and two angles of the triangle are shown. The current is 21 A, and the generator has four poles. The diagram shows per-phase values. (a) Is the generator overexcited or underexcited? (b) What is the rotor power angle? (c) What is the power factor and is it leading or lagging? (d) Determine the synchronous reactance. (e) Determine the input power and torque, ignoring losses. $\bar{E}_f = 150\angle50^\circ$ $50^\circ$ Length = 122.4 V $\bar{V} = \frac{240}{\sqrt{3}}\angle20^\circ$ $110.1^\circ$ Figure P4.30

Section 1a: Answer 3 questions (3 @ 5 pts. = 15 pts.) 1a.1 The three structural frames shown below are hinged at the four corners and are therefore unstable when subjected to a lateral load. Diagram three distinctly different strategies to make each structure stable. You can add members or alter the frames and connections as you determine effective. Note, a mirror image is not a distinctly different solution. 1a.2 Consider the parallel chord truss below which needs diagonals to be stable. Add diagonal members to the truss frame so that all the diagonals are in Tension for the point load shown.
