SA01U: Statically Determinate Beams

[@yonasabate3624]

I have no idea how to express my gratitude for you. This is the most clearly stated lecture I have ever seen.thanks so much!!!

[@DrStructure]

Glad you find the lecture useful, and thanks you for you feedback!

[@madesukrawa7196]

Fantastic. Thank you for the effort to prepare the materials very useful for the engineering students

[@alshookryalsir4707]

Thanks for this gorgeous ❤️ explanation

[@ainembabazidavis8404]

Thanks for making us aware of the types of things forces

[@aduseiebenezer3496]

Thank you. This is so clear

[@199snehamehar8]

plzz share video of stiffness matrix analysis

[@somone5186]

it was really so helpfull thank you so much

[@ayushbharti2621]

Thanks for making such a clarifying video. I just wonder why my college professors do not explain like this ?

[@Ruzbehlp]

7:52 answers are 1) fy=30 M=150 2)Ay=13.75 By=11.25 3)fy=39 M=358 4)Ay=11.25 By=6.75

Tq sir/madam , was very helpful...

[@engrmasroorkhan2407]

Hi sir. your videos are so informative. Can you tell me about stress strain curve in a video lecture??? plzzzz

[@vikramnair874]

Can I know the answers @ 7.59 ?

[@DrStructure]

Click on the i at the upper right corner of the screen for links to solutions.

😀👍

Superb sir can you convert your all video in hindi

[@DrStructure]

Interesting idea. The process of video localization is rather involved and requires participation from Indian civil/structural engineering professors. We’ll look into it.

QA: Ax=0, Ay=30KN, Ma=150KN QB: Ax=0, Ay=12.5kn, By=12.5KN QC: Bx=0, By=39KN, Mb=195KN DR Structure please reply if i am wrong then please explain thank you

[@DrStructure]

The answers you have provided from Problems 2 and 3 are partially correct. For Problem 2, the vertical reaction forces cannot be equal since the beam is loaded more heavily toward the left end. Hence, the left reaction force (Ay) must be larger than By. For Problem 3, the moment of the concentrated load about point B alone is 350 kN-m. So the total moment cannot be 195 kN-m.

@@DrStructure thank you got it from the problems solutions

[@michaellibby3140]

Positive moment is counter clockwise

[@DrStructure]

Please keep in mind that a sign convention is just that, a convention. It is not a law of physics. In our formulations, we can refer to either clockwise or counterclockwise direction as positive. As long as we stick to that convention throughout the process, our computations are going to be correct.
