Mohr’s circle seems to be a very unpopular topic in structural mechanics courses! Some view it as:

• arcane,
• procedural,
• confusing,
• no use in practical engineering
• Why bother with Principal Stresses, Maximum shears etc. – Von Mises is king!! Maybe you don’t want to go back to graphs.

In this webinar Tony Abbey talks about why Mohr’s circle is useful today to help understand:

• What are stress transformations?
• Why do them?

Tony's trying to give Mohr a boost here!
