An alloy is known to have a yield strength of 275 MPa, a tensile strength of 380 MPa, and an elasticmodulus of 103 GPa. A cylindrical specimen of this alloy 12.7 mm in diameter and 250 mm long isstressed in tension and found to elongate 7.6 mm. On the basis of the information given, is it possibleto compute the magnitude of the load that is necessary to produce this change in length? If so, calculatethe load. If not, explain why.

A 12 kVA, 208 V, 60Hz, 4-pole, three-phase, Y-connected synchronous generator has a 5 ohm synchronous reactance. The generator is supplying a rated load at unity power factor. The excitation voltage of the generator was 206 V/phase. If the field current is increased by 20% and the prime mover power is kept constant, what is the new power angle in degrees? Round your answer to one decimal place.
