A reversible motor is used to open and close a gate. The motorhas three terminals: L1A, L1B, and L2. When L2 is connected toground and power is applied to L1A, the motor runs in theclockwise, CW, direction, opening the gate. When power is appliedto L1B, the motor runs in the counterclockwise, CCW, direction,closing the gate. The gate has two limit switches: LS1 is activatedwhen the gate is closed, and LS2 is activated when the gate isopen. Each limit switch has one normally open, NO, contact and onenormally closed, NC, contact. Two control relays, CR1 and CR2, areused in the gate control circuit. These relays have two NO contactsand two NC contacts. A NO pushbutton START switch is used toinitiate the opening of the gate.Draw a ladder diagram that will open the gate after amomentary closure of the START switch, close the gate immediatelyafter the gate is fully open, and turn off the power to the motorwhen the gate is closed. Your circuit must include an interlock feature that will not allow simultaneous application of power to onL1A and L1B.
Two very thin concentric rings lies in the xy-plane with their centers at the origin. The outer ring has a current of 1.5 A in the +uφ direction and has a radius of 50 cms. The inner ring has a radius of 30 cms. The magnetic field at the point (0,..
Show the truth table for the following circuits: a. A 3 input NAND GATE (Inputs are A,B, and C and the output is Q) b. A 3 input odd parity circuit. (Inputs are A,B, and C and the output is Q) c. A two bit adder with inputs (A1,A0 and B1,B0) and outp..
A ‘c-core' inductor has a total air-gap length of 3 mm and a cross-sectional area of 100 cm2. Two coils are wound on the core - one of 500-turns and another of 250-turns. Assuming the iron reluctance, fringing flux and leakage flux to be negligibl..
Wanting to make optimal use of this shared resource, you make some measurements to determine how many cores your simulation can effectively use. You find that one run of your program takes 36 hours to run on 2 cores and 15 hours to run on 8 cores.
a) Detrmine Frequency response of a 3rd order high-pass filter having a cutoff freq at 150hz. b) Detrmine freq response function of 4th order low-pass filter ahving cutoff freq at 600hz.
determine the coefficients c1, C2, c3, ,c4 used for projecting s onto v(1).v(4),respectively Using v(1), v(2) and v(3) only, find s*, an approximation for s using the orthogonal projection method. Determine the error vector s* - s.

Give a single intensity transformation function for spreading the intensities of an image so the lowest intensity is 0 and the highest is L-1.
If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
The integer array and the size of the array are passed into the function through parameters. Do not worry about includes. This is only a function, so there is no main routine. The function should fill the array with valid inputs.
Given the characteristic equation: F(z) = z^3 + z^2 + kz - 0.5 = 0 a) Use the Jury test to determine the range of "k" that ensures the system is BIBO stable. Show any inequality graphs and how they are combined to determine the valid range of k.
The rate of production of ATP in the cell is about 10 million molecules per second. The steady-state number of ATP molecules in the human body is about 0.1 mol. The number of cells of a human body is approximately 1014.
