Pulley Motion Example 2 - Engineering Dynamics

This video is a pulley motion example that uses Pythagorean theorem to describe the length of the cable. Then takes a time derivative to relate velocities and solver for the velocity of a dependent particle

I love how excited you get when you are teaching, it makes me less nervous about my exam. Please upload more videos, never stop!

You have an amazing talent for teaching! I've had the same terrible professor for two semesters now (for statics and for dynamics), and you are the only reason I've been able to get grades as good as I have gotten. You're more my professor than you'll ever know haha. Don't ever stop - You're much appreciated!

This video has been so helpful for understanding dynamics. Thank you so much :)

This isn't even part of my exam, but the tiger piñata made me watch. So cute.

Perfect timing I just about to search for 2D constraint motion problem! Also love the the fact that you make the Material fun by adding a piñata and a dad!

You should do thermodynamics videos, it would be awesome

[mustafaabdulkadir]

good on making pulleys seem more fun than it is!!!

[duhduh]

Could you do one with the acceleration?

Thank you for saving me and helping me understand concepts

[busanii]

Thank you! Made this problem verrry easy, you the best

[dcyugioh]

Awesome videos, consider going as big as Khan Academy.

Where did you state or find that the x distance equals 3?

[ashlyncampbell]

near the end of the video shouldn't the 1/2 and 2 cancel out thus leaving no 1/2 in the Vy equation?

love you vids i just want to ask
how did the derrivative of h^2 become xdot and not 2h
Thanks in advance
