Find Reaction forces for a Beam

[@talhaz5403]

CORRECTION ---> A(y) is = - 14.3 .... or you can say 14.3 (downward direction) (Since upward direction is positive)

[@jeniepalma8713]

Yes I also got -14.3 so therefore, the arrow should be downward direction😊

[@yahirrangel2204]

Upward direction is not always positive it also depends on moment

[@alphafox1307]

thanks britney spears

[@SohanMeegahage]

Thanks for this video it cleared up how to do the uniformly distributed load part

[@concretedream7529]

You are welcome.

[@karimamir-o3w]

this helped me omg i was stuck on a question that required this for the first step and i was stuck for a while and you cleared it up perfectly thank you for existing

[@concretedream7529]

You're welcome.

[@breeannaelliott6695]

This is gold! Thank you for sharing helped a bunch.

[@concretedream7529]

You're welcome.

[@artupaysivar6884]

0:51 how do you decide the direction of the reaction forces (Ax and Ay) on point A?

[@concretedream7529]

You can assume ANY direction you want, and your final answer will tell you the real direction. For example, you assumed that the reaction force in y-dir goes down, after solving equilibrium equation, you got a negative value. This means that the orignal assumption (downwards) was wrong, should be in the opposite direction (upwards). I hope this helps.

[@alyssakayecambronero282]

Thank you so much! This made everything clear for me since we tackled this lesson.

[@concretedream7529]

You're welcome

[@maakuuun6649]

may i ask how would you know if it counterclockwise or clockwise specially on the summmation moment of A

[@concretedream7529]

Yes, please check this video. Start to watch at 1:45 and I use 2 way to explain how to identify the direction of the moment: 1. use pencil 2. right-hand rule.

What type of study are you studying

[@Professor-we5iu]

same question

[@junbautista3880]

What the heck is going on here??? How did you solve those numbers? Hahahah gosh

[@WersiyCollins]

Hi am so in love with the vedio and a clear solution

[@17osefalfanfadhil30]

such a clear explanation thankyou so much

[@syd_jzx100]

[@ezsyafiq1533]

hello mdm,can i know how to contact u because i have sample question to ask

[@parkerthomas2713]

Goooooooooooooooooooood job you are literally so smart!

[@dykensmarcelin902]

She has a pretty good voice and explains very well

[@concretedream7529]

Thanks.

[@dykensmarcelin902]

You're very welcome. You're very talented. Keep it up

[@ibnumubarokeib]

oh yeah, i got loss..

[@bryangacs7188]

Thank you for this. :) You saved me from an hour of frustration

[@concretedream7529]

Glad it helped!

[@kirbypua5088]

How does one achieve such neatness

[@elijahsmart4990]

Good lecturing technique

[@concretedream7529]

Thanks

[@ndounaben]

Keep people with relevant videos, watch How To calculate Reactions at Supports of a Beam; How to check that the Beam is in Equilibrium; How to Draw the Shear Force Diagram; How to Calculate Bending Moments and How to Draw the Bending Moment Diagram: ua-cam.com/video/D-Dxt-yCOlg/v-deo.html

[@concretedream7529]

I tried to put them as a playlist. Maybe you can check that. Thanks

[@geraldpabello2750]

Very clear, thank you!!!

[@concretedream7529]

You're welcome.

[@kspades2530]

Thanks, I forgot about internal moments.

[@diflection1]

Ra= - 14.3

[@fernandoirodriguez8966]

alright good thanks I was freaking out

[@reginaofallwaters]

I was also freaking out lol

[@engineeringvision]

A good educational channel

[@ColonelFluffles]

Within the sum of the moment around a, how can you add up that other moment on the beam (20Nm) even thos that moment is not around a but around another point?

[@concretedream7529]

You're using moment equilibrium equation to find reaction forces which means you will need to include ALL the applied moment (20 N-m) and ALL the forces that might produce the moment at the point you summarized.

[@mdnazmodshakib9998]

Thank you so much

[@NostalgicArabian]

thank you

[@basedanon1353]

what if the downward 8kn force was not given? how would you do then

[@concretedream7529]

In your EofE (equation of equilibrium), moment around A, delete -8kN*3m

[@wardanasim5551]

Thank youuu💙💙

[@ayomikeofe9617]

isn't this a rectangular distributed load? not triangle.

[@wanamirfarhanwanmansor2846]

Thank you very much

[@concretedream7529]

You're welcome.

[@danielaorquiza6888]

Thank you

[@atelford93]

Shouldn't Ay = 14.3 kN ( ↓ ) ?

[@andrewarkar1121]

I have the same answer as you.

[@victorsone9008]

no,
ay= lmao

[@mrj6831]

yes ,Ay will be negative if we take By +ve

[@2a1n71]

Thanks a bunch

[@misbahulganiemon2993]

Thanks

[@zaredkaunajnr3972]

Ray= -14.3kN⬇️

[@nirajburnwal9662]

Thanks a lot.

[@kelvinmanyara1097]

thank you you do this clearly...

[@concretedream7529]

You're welcome.

[@alvinjayursulum9818]

how did you solve icannot get it

[@concretedream7529]

Using the equilibrium equation at A (check Time 2:46), you will notice that By is the only unknown in this equation.

[@smitkumarpatel7224]

Thank you 😊

[@mychannelmyrules6373]

Your voice is so sweet 😍😍😍😍

[@arockianayagam7460]

Awesome😍😍

[@fernandoirodriguez8966]

this comment makes no sense
I didn't listen to the video but I don't think that it makes sense

[@fatimakadiwal8873]

help lot and very easy way soln

[@jdazzld_]

how do ppl understandd this

[@diflection1]

Rb=67.3

[@reymarkdelacruz212]

How can you get 1.5m?

[@concretedream7529]

The centroid of distributed load which is a rectangle will be in the middle.

[@charlesmcguire6498]

That's is 3 divide 2

[@davidindrawes7006]

Everything is wrong!
