I used the law of cosines on all interior angles since it was the formula I was confident and aware of and got 99.3 immediately, so when you used another formula and got another answer I thought I was wrong to use law of cosines on all angles but turns out it was fine. This video really enlightened me on things, thank you sir!

idk if the law of sines is interchangeable but i have always learned to start with the sin on bottom

very informative video.

Brilliant explanation 👍😊💛...

excellent video, thank you!

so helpful thanks alot!

thank you for making this simple and quick video, really helped me!

so helpful, thank you very much!

nice. thanks a lot

I'm so confused about you found an angle a!

You are great man 2 hours i don't understanded from my doctor i get it in 6 minutes

Thank you very much man you are awesome ❤

From which book is this example taken?

Would the shear strain at D be negative since the angle gets larger?

Interesting

In the approximation section should you divide the whole thing with the total area?

i love the way you say" And... we're done!! " great explanation and great attitude 🔥

life changing video ☺

How to derive stress transformation formulae using Mohr's circle? I mean how to geometrically interpret the stress transformation equations from the Mohr's circle

where does 2 over 3 of section 2 coming from ?

I've been searching for this proof for almost 7 hours now. You sir, are my saviour. Gratefully, An engineering student in the UK.

Thank you sir You have saved me for my exam 😭

Why are we using shear stress only and not stress due to bending moment?

4x10 = 40, 40/3.5 = 11.423... 1:14

Never seen this method before in any text books....> It is so easy to follow and very interesting! Can you please refer a textbook that used this method. Thanks! love from JADAVPUR UNIVERSITY🥰😇

You are like a super hero. You always save our day, Thanks

For three concurrent force and they act on same direction you can apply lami's theorem.

This solution is not true. 1st and 2nd pulley torques are in reverse directions so if you assume first pulley static (relative to 1st pulley) and second is rotating. Then 2nd pulley will be 85ft.lb. But as your graph this difference is 55 ft.lb.

Is it just me? The video lectures that I really needed are the ones that I find very late.

You explain how this works very well. Thank you. I've seen a few other sources so far, but they just go through the steps without actually explaining why they are the way they are.

How can we find the elongation if the stress in the cable is larger than yield stress?

Is hilarous how this guy talks identically to patrick bateman 😂

i think the y bar for Q should be 0.15m

'WOW you should just teach every class in the world very well explained and clear!. Even the tone of voice is pleasant to listen. Subscribed!

amazing video; i finally understand the concept!

This voice makes me uncomfortable

Best lecturing ❤

Very cool

There is no escaping reason; no denying purpose. Because as we both know, without purpose, we would not exist.

engineering is much more difficult if you use freedom units...USA!

Im confused I see how you solved for Fbc by excluding the final part and grouping it together at the end. However, The reason IM confused is because if you consider the final part with just Ax, Ay, And Fbc. Fbc has to be zero otherwise it would create a moment about a. Unless the bucket has a weight but I think that should be included in the diagram and cant be assumed!

What about a transverse load in the connection between the two materials?

Your channel and knowledge is very helpful. Thank you and have a good life.

Best Explanation ever on stress transformations

this was unsymmetrical bending of symmetrical parts! thumbs down!

Question: Why use the longitudinal stress formula, and not the hoop stress formula sigma=Pr/t. If you use this, you get a thickness of about 0.21 inches. Why is it safe to use the Pr/2t formula?

I love how my professor is so lazy she can't teach this in class.

Best explanation and easily understandable

This is assuming euler's buckling method. Make sure you double check whether or not that method is valid. If not use Johnson instead.
