TRY OUR GRADUATE-LEVEL INTEGRITY QUIZ

If you are interested in integrity-related subjects, have a try at our graduate-level quiz. The questions are not linked to any specific exam or qualification but contain general principles of physics, science and maths that form the basis of engineering degree courses.

As with all the technical quizzes on our website, have a go at each question first, before you look at the suggested answers via the link at the end. See how you do.

Qu 1: The fastest wheels in the world: Rotating masses

The new Bloodhound supersonic car will attempt to be the first car to reach 1000mph.It has solid wheels made out of aluminium. You can see the details here www.bloodhoundssc.com/project/car/wheels/desert-wheels.

The Bloodhound wheels are 910 mm diameter. If you stuck a 5 pence piece (weight 3.25g) to the rim, how much would if ‘weigh’ when the car was travelling at 1000mph?

Qu 2: Economical design

In the world of engineering design there are only three geometrical figures with equal sides that can fit together on a flat surface without leaving gaps. They are equilateral triangles, squares, and what’s the other one? Once you’ve got it, can you think of an example where you could find it designed by nature?

Qu 3: Entropy: states of disorder

Generations of engineering students, and some lecturers, have entered and left university without really understanding entropy; a measure of the state of disorder of a system. You have an entropy-machine in your house; your refrigerator. Here’s the question.

Does the operation of your refrigerator act to increase entropy or decrease entropy?

Qu 4: Alloying elements in metals

Which of these alloying elements is the odd one out?

• Sodium
• Magnesium
• Vanadium
• Silver

Can you handle The MATTHEWS MASTERCLASS?

If you enjoyed this graduate-level quiz then why not try the Matthews Integrity MASTERCLASS challenge quiz and see how you do against our other website visitors.

It’s a test of your knowledge of Integrity Code and technical knowledge across several levels and type of equipment so it has a strong engineering bias rather than being purely academic. To match its MASTERCLASS designation you can’t expect it to be easy; in fact it is purposely designed to be tough. If you want to compete with your peers in the integrity industry, and see how good you really are, then just click the MASTERCLASS QUIZ
