This is done with a combinational circuit that has five inputs: S1 through S4 and C4, and three outputs, designed by x, y, and z, so that x = 1 if A = B (S = 0000) y = 1 if A < B (C4 = 0) z = 1 if A > B (C4 = 1 and S ≠ 0000) (a) Obtain the function for x, y and z respectively. (b) Design this combinational logic circuit with minimum number of gates. The combinational circuit can be implemented with the 7404 and 7408(or 7432) ICs. (c) Construct the comparator circuit and test its operation. Use at least two sets of numbers for A and B to check each of the outputs, x, y, and z.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
