Find a minimum two-level, multiple-output AND-ORgate circuit to realize thesefunctions (eight gates minimum).f1(a, b, c, d) = Σm(10, 11, 12, 15) + Σd(4, 8, 14)f2(a, b, c, d) = Σm(0, 4, 8, 9) + Σd(1, 10, 12)f3(a, b, c, d) = Σm(4, 11, 13, 14, 15) + Σd(5, 9, 12)

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.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
