Derive the state space equation of a DC motor with:
1)supply voltage and load torque as inputs and2)armature current, angular speed as outputs.
A 20-Hp, 240VDC, 4-pole Shunt motor operates at rated load and 1700rpm and an efficiency of 88%. It has armature resistance of 0.2Ω and field resistance of 240Ω. Find: a)Power input to the motor b)IFLA of the motor
The time to failure of fluorescent lights in a large office building is exponentially distributed with a failure rate of 0.03125 hours. How many spare tubes must the building custodian maintain to have at least a 0.95 probability of replacing all..
The ALU required for this lab accepts two 4-bit inputs (A0 - A3, B0 - B3), a 3-bit function selection code (F0 - F2) and outputs a 5-bit result (S0 - S4). Since the function selection uses 3-bits, there are 8 different functions.
Need to use multisim and proteus and have build the circuit diagram on multisim and proteus, also have the program written, all u need to do its simulate it and take the necessary results.
under insolation conditions 500 W/m^2 (direct sunlight), and 10% solar cell efficiency, calculate the area required for a photovoltaic array capable of running an electric vehicle driven by a single 40 hp motor for 3 hours at half power
assume filter is connected to a pure resistive load. The cutoff frequency is not to drop below 25krad/s. What is the smallest load resistor that can be connected across the output terminals of the filter.
The reliability performance of each microprocessor is based on the exponential reliability distribution with the following failure rates: A = 23.5 × 10^-3 , B = 12.5 × 10^-4 , C = 12.5 × 10^-4 and D = 23.5 × 10^-3
Bit 4 of Port B is connected to a switch that normally outputs a zero. Monitor this switch to detect a change from zero to one. Immediately when it becomes one, call a function to toggle Bit 5 of Port B, which is connected to an LED
The voltage across a 1x10^(-6)F capacitor is given by v(t)=100e^(-100t) in which time t is in seconds. 1. find an expression for the current 2. find an expression for the power 3. find an expression for the stored energy
A 1.80kg , horizontal, uniform tray is attached to a vertical ideal spring of force constant 195N/m and a 290g metal ball is in the tray. The spring is below the tray, so it can oscillate up-and-down.
Find the inverse z-transform, x(n), of the following functions by bringing them into a form such that you can look up the inverse z-transform from the tables. This will require some algebraic and /or trigonometric manipulation/calculation.
A 1 lb weight is suspended from a 0.005 in diameter wire. The unstrained resistance of the wire, R0, is 270 ohm, and its unstrained length is L0=36 in. The wire's gauge factor is 3.2. a. Calculate the psi tensile stress on the loaded wire.
