Why is the reflection step in the engineering process the most important step?

1 answer:

6 0

Reflection helps designers to learn from their experiences, to integrate and co-ordinate different aspects of a design situation, to judge the progress of the design process, to evaluate interactions with the design context, and to plan suitable future design activities.

Write a function called largest3 which takes 3 numbers as parameters and returns the largest of the 3. Write a program which tak

tamaranim1 [39]

Answer:

The solution code is written in Python.

def largest3(num1, num2, num3):
largest = num1
if(largest < num2):
largest = num2
if(largest < num3):
largest = num3
return largest
first_num = int(input("Enter first number: "))
second_num = int(input("Enter second number: "))
third_num = int(input("Enter third number: "))
largest_number = largest3(first_num, second_num, third_num)
print("The largest number is " + str(largest_number))

Explanation:

Create function largest3

Firstly, we can create a function largest3 which take 3 numbers (num1, num2, num3) as input. (Line 1).
Please note Python uses keyword def to denote a function. The code from Line 2 - 10 are function body of largest3.
Within the function body, create a variable, largest, to store the largest number. In the first beginning, just tentatively assign num1 to largest. (Line 2)
Next, proceed to check if the current "largest" value smaller than the num2 (Line 4). If so, replace the original value of largest variable with num2 (Line 5).
Repeat the similar comparison procedure to num3 (Line 7-8)
At the end, return the final value of "largest" as output

Get User Input

Prompt use input for three numbers (Line 13 -15) using Python built-in input function.
Please note the input parts of codes is done outside of the function largest3.

Call function to get largest number and display

We can simply call the function largest by writing the function name largest and passing the three user input into the parenthesis as arguments. (Line 17)
The function largest will operate on the three arguments and return the output to the variable largest_number.
Lastly, print the output using Python built-in print function. (Line 18)
Please note the output parts of codes is also done outside of the function largest3.

a cubical box 20-cm on a side is contructed from 1.2 cm thick concrete panels. A 100-W light bulb is sealed inside the box. What

Flura [38]

Answer:

Temperature on the inside ofthe box

Explanation:

The power of the light bulb is the rate of heat conduction of the bulb, $dq/dt = 100 W$

The thickness of the wall, L = 1.2 cm = 0.012m

Length of the cube's side, x = 20cm = 0.2 m

The area of the cubical box, A = 6x²

A = 6 * 0.2² = 6 * 0.04

A = 0.24 m²

Temperature of the surrounding, $T_0 = 20^0 C = 273 + 20 = 293 K$

Temperature of the inside of the box, $T_{in} = ?$

Coefficient of thermal conductivity, k = 0.8 W/m-K

The formula for the rate of heat conduction is given by:

$dq/dt = \frac{kA(T_{in} - T_0)}{L} \\\\100 = \frac{0.8*0.24(T_{in} - 293)}{0.012}\\\\T_{in} - 293 = \frac{100 * 0.012}{0.8*0.24} \\\\T_{in} - 293 = 6.25\\\\T_{in} = 293 + 6.25\\\\T_{in} = 299.25 K\\\\T_{in} = 299.25 - 273\\\\T_{in} = 26.25^0 C$

Name the main classes of polymer and define their characteristic properties

Svetlanka [38]

Answer:

Polymers are the naturally occurring or synthetic macromolecules that are composed of repeating subunits, called monomers.

The three main classes of polymers are: thermoplastic, thermosetting, and the elastomers.

Thermoplastic polymers have linear bonding. These polymers can be melted again and thus can recycled.

Thermosetting polymers have cross-linked bonding. These polymers decompose when heated and thus can not be remelted and recycled.

Elastomers have linear bonding with some cross-linking. These polymers extreme elastic extensibility and thus can revert back to its original shape after deformation, without causing any permanent damage.
