Your videos have helped me through Statics, Strength of Materials, Structural Analysis, and Indeterminate Structures.

I am an engineer now, but still in school. I can't thank you enough for all the times you've helped me over the years!

[mohamedkhalid]

I love the way you explain the whole thing. Simple and easy ! Thanks

[rma]

Keep it up professor 💪💪 you’re doing wonders for us mechanical engineering students

[sshep]

Can you make a video explaining why projection is used as opposed to cylindrical contact area.

[navidahmed]

ohh may daysss, finally the best professor is back.

[gabewinter]

In this course right now, perfect timing

[PeterParker-szvm]

This is the best explanation I've heard!! Absolute life saver. Sending love from new zealand

[CRatcliffe]

Miss you dr Hanson! Hope all is going well at tech!

[manuboker]

Wonderful solids lessons!! really taking the time to explain the problems along with a good sense of humor :))

I have a question. At 10:20 he assumed to measure Fab as Fab(cos50) but wouldn’t it be cos40 bc you measure the angle from the horizontal? Someone please clarify thank you!!

[owencarlisle]

Need to keep up the videos. Once per week would be epic if you can sir. You were thinking of moving onto other topics once upon a time 😊

Hi, professor. Why the area in the bearing stress isn't 3.14(4.5)(15)? because it's half the perimeter times the thickness, that the surface that the bold hold the force with it.

[DaryaDelaram-xx]

is it ok to use the same force for both shearing and bearing?cause bearing is normal strress and shearing is not

[javierumana]

@9:24 why did you make F_ABsin50 on the horizontal and F_ABcos50 on the vertical. Initially I paused the video and went ahead and did my own calculation but with the moment at point B. I Got stumped not realizing you had your sin and cos mixed up. If I recalculated my moment to have it at point C, I realize I wouldve got the same answers as before. So im just lost on why x is sin and y is cos.

[famueduyou]

So how do we find the normal stress here? What should be the area for Normal Stress?

[charbelbassil]

hello, here in this video, we didn't transform from mm to m because we are dividing in the end and it will simplify true??

[joeking]

Can someone explain how he arrived at the angle 20 at F(AB) to get the overall angle of 50 deg?😪😮‍💨☹🥴😖😫

[AlbertVathapally]

For A I got 702.47Pa, since I converted the mm diameter to m when calculating area. How is my answer wildly different from yours?

[alanlopez]

I'm still struggling to understand why you have to find the resultant force at pin A and then divide by the area. I thought the shear force was only on the "y" direction

Come on, man. I just graduated. Where were you 7 months ago??
