Technician A says that primary vibration is created by slight differences in the inertia of the pistons between top dead center and bottom dead center. Technician B says that secondary vibration is a strong low-frequency vibration caused by the movement of the piston traveling up and down the cylinder. Who is correct? O A. Neither Technician A nor B OB. Technician B O C. Both Technicians A and B D. Technician A​

Answers

Answer 1

Neither technician Technician or  B is correct in the statement above.

What leads to primary vibration?

Vibration is a factor that is said to be caused by one or more other factors that occur together at any given time.

This can be due to actors such as imbalance, misalignment, wear and looseness and others. An imbalance  occurs due to  a "heavy spot" that is found inside a rotating component and it will lead to vibration when the unbalanced weight is said to rotates in circles round the machine's axis.

how to study thermodynamics?​

Answers

It is study of the relationships between heat, temprature, work and energy

Thermodynamics is one of the few engineering courses that I would say are more conceptual than computaional. I can not emphasise how important it is to fully understand thermodynamic terminology and process. Once you understand those any problems can be easily worked out.

What I recommend is that you go through you thermodynamics book and read it carefully highlighting the important points and summarizing them in a spare notebook. The first few chapters are full of indroductory concepts such as the state of a system, processes, closed and open systems, etc. That I reccomend you memorize(with understanding ofcourse) as these are carried on all throughout.

As chapters get more complex I recommend flow charts and mind maps with as much condensed information as possible.

Declare a variable and increment with a while loop until the variable is not less than 5Create a function that returns the product of two numbersUses the new keyword to create an array

were written in JavaScript and are found in the attached images

Declaring a variable

The first code declares a variable called num and gives it an initial value of 0. It then enters a while loop that lauches a message box (using window.alert) to print the message "Keep going" as long as num remains less than 5.

If nothing is done within the loop to increment num towards the value 5, the loop will go on endlessly notifying the user to "Keep going".

So, an increment of 1 was added to the loop body to increment the variable num. This makes sure the loop terminates.

Creating a function that returns the product of two numbers

Here, a function was created that receives two arguments (n1  and n2), then returns the product (n1 * n2)

Declaring an Array

This last code segment creates an array using the new keyword. The new keyword is generally used in constructing objects.

In this case the object constructed is an array having three strings;

In hexadecimal - [tex](1FFF)_{16[/tex]

B) Signed number

The largest signed no can be represented with 13bit as

Mass = m = 3.0 tones

- 1 ton = 1,000 kg

= 3.0 × 1,000

= 3,000 kg

volume = v = 4m^3

Required:

Mass density of oil = p = ?

We know that;

A 100 MHz generator with Vg= 10/00 v and internal resistance 50 ohms air line that is 3.6m and terminated in a 25+j25 ohm load

Answers

The value of Vz at point z from the generator  = 17.748 ∠ -107.62°  V

Given data :

Internal resistance = 50 ohms

Vg = 10 ∠ 0° v

length of air line = 3.6 m

Terminating resistance = 25 + j25 Ω

First step : Determine the Total impedance

Total Impedance ( z ) = Rin + Rline + Rl + jXl

                                   = 50 + 50 + 25 + j25  

                                   = 125 + j25  ≈ 127.47 ∠ 11.3°

Next step : Determine the current in the circuit

current ( I ) = Vg / z

                  =  ( 10∠0° v ) / ( 127.47 ∠ 11.3° )

                 = 0.0784 ∠ -11.3  amp

Final step : Determine the value of Vz at point z from the generator

Vz = ( Vg + I * Ri ) - ( RI * I + Rline * I )

    = ( 10∠0° + 0.0784 ∠ -11.3  * 50 ) - ( 25 + j25  + 50 * 0.0784 ∠ -11.3 )

    = -5.37 - j16.91  ≈  17.748 ∠ -107.62°  V

Hence we can conclude that the value of Vz at point z form the generator 17.748 ∠ -107.62°  V

In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.

A student borrows $60,000 for business school at 6.5% stated annual interest with equal monthly payments over 10 years. Consider this as a loan with no payments or interest during school so that the problem structure is equivalent to a standard loan received one period before the first payment. How much is the monthly payment?

Answers

Answer:

  $681.29

Explanation:

The amortization formula seems to apply. The monthly payment on a loan of P at rate r for t years is ...

  A = P(r/10)/(1 -(1 +r/12)^(-12t))

For the given loan parameters, the monthly payment is ...

  A = $60,000(0.065/12)/(1 -(1 +0.065/12)^(-12·10)) ≈ $681.29

The monthly payment is $681.29.
