Can't thank you enough for this videos. I've done several forms of online learning before the shutdown and I have to say this is by far one of the best series for self learning. I am a BSME and I am stuck working full time and going to doing engineering courses full time this semester so I've been using this month to get as far ahead as possible to reduce my study time. Highly entertaining stuff. You remind me of my honors intro to engr professor at Purdue. Thanks again for being a such a great and free source of material during these trying times.

System-solver coming in clutch? nah you're coming in clutch!! thank you for these videos

[gaberillman]

Thank you so much for doing this problem specifically, Jeff! My Statics Professor not only chose this problem for our chapter 3 particle equilibrium quiz, but he also included a problem just like this on our first exam.... for some reason I have a feeling this is the problem he will want to include for our final exam lol

[pavlypoktor]

why is the angle in BC and DE the same? it seems from a visual view DE would have a higher degree.

Professor Hanson, thank you for another solid explanation of Equilibrium of a Particle. Solving problem continues to be the key to understanding mechanics.

[lilbeing]

OK teacher, you won, I love mechanics engineering now. WOW MAGICAL, thank you so much deeply, really!!

[billhensley]

Really great videos. I’m also an engineering student, however I got lost when Jeff summed the forces to come up with 1154.7 Newtons. Can someone provide some guidance on this?

[helenday]

So helpful, thank you. It filled in a few gaps in my knowledge & thus helped to clarify questions that were puzzling me before. For example, the way the video explains how tension is the same on both sides of a pulley. All delivered with a great, individual and likeable style.

[carlosnataren]

How does Jeff summed the forces to come up to 360.95 N? Can someone show me the steps, I appreciate it.

[smithyyow]

I dont get the last part can you explain it how is it equal to 1154.7 and 360.95???

[milascerenhoke]

Hi, love your work! But why did we assume the Tension Force around the pulley acts on the center, same with the Force PE? Shouldn't we at least mention that our solution is in equilibrium under this condition?
Or is Tabc really acts on point D? Can you clarify please? Thank you.

@jeffhanson Hello! I just wanted to thank you for these videos, they are a life saver. However, I was wanting to know when you use your system solver feature on your calculator, how do you know x is the cable T(abc) and y is the Force (de) in this problem? Since they both have components from both the force and tension?

[mohammedalkhliwi]

How did you come up with the final answer, not sure how to do it w/ the calculator

[xxcamicakexx]

How can i finish the problem at 9:41 without a system solver? My calculator doesn't have one.

[samuelotono]

Thank you very much for these videos, but one question though, why are you assuming the forces are in 2-D space? In real life is this applicable?

[fiona.e]

Idk why the force p has the same angle as the tension can someone explains to me

[dontworry]

What is a system solver? How do I figure this out on paper?

[farhadjoya]

There are two T.
One is T shorter and one T is longer.
My question is which TBC or TBA has more tension?
Why the then is equal in TBC and TBA ?

[abdulahadhussain]

Plz explain why dod we take both the tension of ropes T like why did we assume that both parts of the rope have same force T?

[syeduzair]

Sir, doesn't the weight lifted downward multiplied by 9.81 as mentioned in the book hibbeler?
