(adsbygoogle = window.adsbygoogle || []).push({}); SUPER CONFUSING linear algebra question :)

1. The problem statement, all variables and given/known data

I have attached a picture of the question with a solution.

3. The attempt at a solution

Well... First i found the parametric equation of the vector L... Yeah...

So even looking at the solution I am confused. I get the conversion that they made to rad/s but the steps after that blow my mind :|. What does omega mean and also why did they multiply by (1,1,1) and then took the cross product of this point and the direction of the rod?

I want to get through this step by step.

Thank you!!
