Engineering students in lab coats discuss an experiment

In the lab: what would you put in the introduction?

In this quiz, we’ll show you excerpts from a report. You’ll be asked to decide whether the information should go in an Introduction section - or not. Don’t be afraid to have a go - the quiz won’t count towards your overall course progress but should help you to better understand what goes in an Introduction section.

Quiz rules

  • Quizzes do not count towards your course score, they are just to help you learn
  • You may retake the quiz as many times as you wish to answer all the questions
  • Select what you consider to be the correct answer to each question and click the "check my answers" button at the bottom of the page.
  • How you did, as well as the feedback, will appear below each question.

Question 1

Would the following information be suitable for an Introduction section?
Samples of the metal under consideration will be fractured using a Charpy impact tester. The Charpy tester was developed in the 1940s and can be used to test samples of metal as well as a variety of other materials. This test has the advantage of being relatively cheap and quick to perform.
Yes
No

Question 2

Would the following information be suitable for an Introduction section?
There are differences between the results obtained from the experiment and those predicted. A potential cause the discrepancy is the change of sample temperature during transit from the thermal environment to the Charpy machine and during the setup of the test.
Yes
No

Question 3

Would the following information be suitable for an Introduction section?
Material fractures can be characterised as either brittle or ductile. Typically, it requires greater impact energy to break a material with a ductile fracture than a brittle fracture.
Yes
No

Question 4

Would the following information be suitable for an Introduction section?
The fracture surface of the steel sample tested at 200°C, as shown in figure 4.8, displays characteristics of a ductile fracture.

The fracture surface of a steel sample impact tested at 200°C

Figure 4.8: The fracture surface of the sample tested at 200°C.

Yes
No

Question 5

Would the following information be suitable for an Introduction section?
A sample was lowered, with tongs, into a vessel of dry ice (at -80°C) and left for sufficient time to reach equilibrium temperature.
Yes
No

Question 6

Would the following information be suitable for an Introduction section?
A rectangular sample is notched and placed between the anvils of the Charpy machine, with the notch facing away from the pendulum, and centred using the locating prong.
Yes
No

Question 7

Would the following information be suitable for an Introduction section?
During this experiment samples of metal at varying temperature were fractured using a Charpy impact tester. The aim of the experiment was to determine the ductile to brittle transition temperature.
Yes
No

Question 8

Would the following information be suitable for an Introduction section?
Previously conducted Charpy impact tests on steel (Tanguy, 2005) and stainless steel (Sutar, 2014) provide comparison data for the work conducted here.
Yes
No
