SA58: Analysis of an Indeterminate Tapered Beam using the Slope-Deflection Method

Great work, Dr.structure

[@Deltadigit]

Great video and great analysis

Excellent video. I've watched your other videos and I really appreciate your method of teaching. I realize this channel focuses on structures and strength of materials, but I was wondering if You were planning on making some videos on differential and integral calculus? A firm base in mathematics is required to be able to understand, but unfortunately in schools Calculus is taught non-intuitively, to solve through plugging-and-chugging. I wish You'd apply your talent even beyond your structural videos, which are once again amazing. Cheers

Thanks for the note. You are absolutely right, in our schools, (engineering) mathematics is often taught in a non-intuitive way which makes its comprehension, beyond memorization, a challenge. Introducing math lectures into our library in an integrated manner poses a few challenges, but we will continue to explore ways to make it a reality.

@@DrStructure I'm looking forward to the day when you do make it a reality!

The reaction solutions at 6:13 do not seem to satisfy moment about A = 0, as -200*5 + 106.75*10 - 33.75*18 = -540?

[@DrStructure]

Thanks for pointing out the typo. The vertical reaction at B is the sum of two numbers: 127 + 33.75 = 160.75, NOT 106.75.

[@civl112]

@@DrStructure Thanks. So the answers are RA = 127 up, RB = 160.75 up, RC = 33.75 down (kN)? Their sum do not exactly counter the 200 from UDL...

[@DrStructure]

The error in the results originates from the previous screen. @5:55, the calculated shear values are correct. But notice that, at the bottom of the screen, Vba and Vab are swapped. The shear at A is written as 127, it should have been 73. And the shear at B should be written as 127, not 73. That is why we ended up with incorrect support reactions. The correct reactions are: Ra= 73 (up), Rb = 160.75 (up) and Rc = 33.75 (down).

How do you make such wonderful illustrative videos?

[@DrStructure]

A few pieces of technology and a whole lot of desire to put them to good use.

[@UrbanIndianVlog]

@@DrStructure Please tell me the softwares which are used in making the videos

[@DrStructure]

Adobe Illustrator for creating written text and drawings, Reallusion software products for 3D character creation and animation, and Camtasia Studio for video production.

@@DrStructure Thank you Dr. Structure.

very excellent professor.. sir you are from?

[@issegarawan5716]

Venkatesh janakiraman its madam and she from a hardware.

+isaac mo hello I know it is a female voice.. I don't want to know about the automatic voice.. I just want to know who is the professor this subject and where he is from? right

[@DrStructure]

Please visit Lab101.Space for the information you are looking for.

[@venkatesh2285]

+Dr. Structure thank u so much sir.. happy to know about the professor sir.. convey my wishes to sir.. he is one of the best professor in the world...

[@lakshmanmodi3582]

Plz tell me software name for making these video plzz

[@DrStructure]

The 3D model of the bridge was done using SketchUp. The 3D avatar was created and animated using Reallusion software products. The lecture notes were generated and animated using Adobe Illustrator. Audio/video synchronization, and final video production was done using Camtasia Studio.
