Abalanced y-connected load having an impedance of 60 - j45ω/ϕ is connected in parallel with a balanced δ-connected load having an impedance of 902√∠45∘ ω/ϕ. the paralleled loads are fed from a line having an impedance of 2 + j2ω/ϕ. the magnitude of the line-to-line voltage of the δ-load is 240 3√ v.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
