Use a Karnaugh map to build a circuit that receives 4 inputs A3, A2, A1, A0 and outputs 1 if either A3 ≥ A2 ≥ A1 ≥ A0 or A3 ≤ A2 ≤ A1 ≤ A0. Otherwise the output is 0. For example on input A3A2A1A0 = 0111 the output will be 1, on input A3A2A1A0 = 1100 the output will be 1, and on input A3A2A1A0 = 0101 the output will be 0. You are required to represent the function using a Karnaugh Map, to derive a simplified algebraic expression using the K-map, and to implement (i. e., draw) the corresponding circuit. You may use MUXs and/or decoders in your circuit implementation.

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.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj

Air enters a horizontal, constant-diameter heating duct operating at steady state at 290 k, 1 bar, with a volumetric flow rate of 0.25 m°/s, and exits at 325 k, 0.95 bar. the flow area is 0.04 m2. assuming the ideal gas model with k = 1.4 for the air, determine (a) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer, in kw flow rate, in kg/s, (b) the mass kg 0.3
