Welcome to PF.Homework Statement::What is the importance of rotational dynamics and conservation of angular momentum in various engineering fields?

Relevant Equations::N/A

Please help to answer this question, I don't know how to start, thanks in advance.

We cannot offer tutorial help until you show your best efforts. Can you define "rotational dynamics" and "angular momentum"? Where do you see them come into play in, for example, Mechanical Engineering?

Can you mention two purely rotational machines that have become very important to developed human societies?

No, no; those are parts.Pistons, cogs.

Whole machines which internal moving parts only rotate around a shaft (no reciprocating parts).

No, that is your assignment. You seriously can't think of any machines that we use every day that involve rotational motion? Walk outside and look around...Can you give some examples?

Woo-wee, beats me! I'll wait until the OP figures it out...What was the crank connected to? Hint: It's an eight-lettered F-word.
