Less pretty pictures than Steinberg, but a nicer one for finding your hot spot and an intro to finite element modelling,
and FOR FREE

I have been quickly through this reference. Certainly a good summary, but Steinberg's book walks you through a lot more
real life examples with more practical details and way more cases. I don't think this reference is a nicer one for finding hot spots. Steinberg has all examples in british and cgs ( decimal)units which is handy.
There is also a finite element chapitre and vibration and stress is addressed in a second book. Major advantage of second reference: it is free

There is an old story, perhaps more than 100 years old about Thomas Edison.
Apparently, he was breaking in a new employee, who was very strong in math skills.
Edison gave him the assignment of finding the total interior volume of a specific light-bulb.
The new employee went to work modeling mathematical equations.
Edison returned, poured water into the empty light-bulb body, and measured it out in a liter flask. Does this compare to what is being said here, today?

We have a saying in French: Comparaison n'est pas raison.

The translation is straightforward as well as the meaning.
