Answer:
The charpy test is used to determine amount of energy a material absorbs at fracture.
Explanation:
Charpy Impact test was developed by a French scientist to determine the amount of energy a material absorbs at fracture hence giving the toughness of the material. It is widely used in industrial applications since it is easy to perform and does not requires sophisticated equipment to perform.
The test is performed when a swinging pendulum of known weight is dropped from a known height and is made to strike the metal specimen which is notched.The notch in the sample affects the results of the test hence the notch should be standardized while performing the test. The qualitative results obtained can also be used to compare ductility of different materials.
Answer: There are two kinds of internal combustion engines currently in production: the spark ignition gasoline engine and the compression ignition diesel engine. Most of these are four-stroke cycle engines, meaning four piston strokes are needed to complete a cycle.
Explanation:
Answer:
Dr. Engelbart, who would later help develop the computer mouse and other personal computing technologies, theorized that as electronic circuits were made smaller, their components would get faster, require less power and become cheaper to produce — all at an accelerating pace
The code to
- Declare a variable and increment with a while loop until the variable is not less than 5
- Create a function that returns the product of two numbers
- Uses the new keyword to create an array
were written in JavaScript and are found in the attached images
<h3>
Declaring a variable</h3>
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 <em>window.alert</em>) to print the message "<em>Keep going</em>" 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 "<em>Keep going</em>".
So, an increment of 1 was added to the loop body to increment the variable num. This makes sure the loop terminates.
<h3>
Creating a function that returns the product of two numbers</h3>
Here, a function was created that receives two arguments (n1 and n2), then returns the product (n1 * n2)
<h3>
Declaring an Array</h3>
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;
- my <em>nickname</em>, and

Answer:
Clock input( or Timer Oscillator) in used to change the state of the output.
Explanation:
Flip-flop is an device that is the state changes with the rising or falling of the clock. It has a control signal (clock) input that stores the input state and outputs the state only in response to the clock signal.
The output changes with the change in the input in synchronization with the clock.
Whenever the input of the clock changed, it will result in change in the output.
