Hi we know the angular velocity is always - r x V. The angular velocity is maximum when V is perpendicular to the link, therefore we always want the perpendicular velocity vector. The sign convention is based on the right hand rule. Clockwise is negative counterclockwise is positive.
You might be confused with perpendicularity in this case (that the velocity has direction of link towards O2) because it is Vb/a to be precise, so this is the velocity of point B relative to the point A.
Here’s part 2 using that handbook method. Knowing how to do it this long way will definitely help if it’s a linkage system of any sort often tested under dynamics. ruclips.net/video/SkOdnyprWJs/видео.html

Thank you for this amazing material.
You’re welcome! Thank you for watching and for your practice!
why did you assume Vb is always perpendicular to the link at13:40? and also how can we determine the sign of ω3 and ω4? Thank You

@@directhubfeexam thank you.

in solidworks how can i introduce rpm in mechanism from given data ??
I am studying for the mech FE right now and I could not get this consent no matter how much I tried until I saw this video. Thank you!
I’m glad this helped !
Have you took the test yet??
Good stuff. Thank you!
Quick Question, why did you solve this using vectors when the exam handbook provides an equation that can be used for this situation?

@@directhubfeexam got it
would we get a question this long on the FE exam knowing that there's so many questions and so little time???
@@farooquenadeem5300 Not this long. But definitely know the concept here.
thank you very much
You’re welcome!!
Thank you sir!
You're welcome, don't forget all the necessary equation are in the FE Handbook! Take care.
@@directhubfeexam Will do. More power!
