Welcome to PF.

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?

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

Pistons, cogs.

No, no; those are parts. :smile:

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

Can you give some examples?

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...

In the old days, starting a car involved hand-cranking until electric starter motors replaced the cranks. What was the crank connected to? Hint: It's an eight-lettered F-word.

Woo-wee, beats me! I'll wait until the OP figures it out...
