A. Two machinery options are described below. Calcuate the present value of each of the items specified. Assume an interest rate of 6% and a useful life of 8 years. Show all the necesary work to calcualte value.
Option1 = The inital purchase proce of the machine $25000. The salvage value at the end of the useful life will be $5000. Maintenance cost are $2000 first year and increase 0 per year.
Option 2 The machine is leased for an initial payment of $2000 plus annual payments of $3500. There is no savage vakue. A maintenca contract is purchase for a single payment of $10000 at the start of the lease period.
B. What is the equivalent annualized total cost,over the 8 years lifetime, for the machibe with the lowest present value of lifecycle cost.
A sinusoidal voltage with a peak-to-peak value of 15 v is applied to an RC high-pass filter. If the reactance at the input frquency is zero
A windmill has a diameter of 3 meters. It converts wind enegry to electrical enegy with a efficiency of 40% of the theoretical maxium for windmills. What is the eelctric power output at a wind velcity of 15 miles per hour.
Shielding Effectiveness with copper and steel at equality, Determine the frequency at which two 1 mm thick shields, one made of copper and the other of steel
What are the types of motor Which motor is user in Car Engines which is the most efficient motor How much electricity is needed for single rotation of general motor
Assuming that ideal filters are available, what is the lowest frequency at which the signal can be sampled and subsequently recovered in its analog form without distortion using a low pass filter?
1) Ohm's. Law is considered one of the key foundation in electronics . Why (2) Why do we have to build and test circuits when we have simulation tools
What is the bandwidth occupied by this signal, and the noise bandwidth of the receiver for this signal? Find the BER at the receiver output and the average time between errors.
A ball is shot into the air at 30 degress above the horizontal. It's initial Velocity is 5m/s and lands at the same height that it is launched from. How far does it travel horizontally
Understanding low, high and band pass filters, A signal in the IF section of an FM radio receiver occupies the frequency band 10.61 MHz to 10.79 MHz. Compute the bandwidth of this signal.
Design a counter that will execute the numerical sequence 0, 2, 4, 6,repetitively. Unwanted states should be directed into wanted states that give the simplest logic functions. - Identify the number of required JK D-FLIP FLOP;
A combination of silver/silver chloride and cadmium electrodes are used for biomedical application. a.) Estimate the half-cell potentials of each of the electrodes assuming the potentials don't change between 25deg and body temp.
An analog signal xa(t), band-limited to 5 Hz, is sampled at a rate of 10 samples per second to give a discrete-time signal x(n) = xa(0.1n). The discrete-time signal x(n) is then filtered with an digital FIR filter, h.
