Engineering Analysis Problem

As part of our problem solving training course we sometimes get asked to evaluate machinery and processes. This is to establish the root cause of the failure which sometimes involves some interesting investigational work.

Take a look at this problem which we recently came across and see if you can establish some details about what happened here.

What Happened Here?

The shaft below has been broken into 2 pieces, one half is shown at the failure edge. Use your engineering skills to analyse what contributed to the visual marking and hence deduce the root cause of the break. (Hint: there are five failure modes visible, start by identifying them and then work out the correct sequence).

Broken Shaft

We will post the answer along with our next blog.
