Finite Element Method 1D Problem with simplified solution (Direct Method)

For 1D Tapered bar or self weight problem refer following video

Correction
sigma 2 = 50 MPa
sigma 3 = 100 MPa

[balogunrachael]

Well explained
Thanks
Stress 1=150mpa
Stress 2 = 50mpa
Stress 3= 100mpa


Thanks so much

when this video explained it better than my prof ever did throughout the entire semester

[prashantilalashettar]

this is nice video for basic learner but stress2 valu 50N/mm2 and stress3 valu 100N/mm2 its ok manage able thank you for good explanation

[skb-du]

thank you sir, very clear and concise explanation 👍
but the last two stresses values are 50 MPa and 100.262 MPa

[panda]

Stress 2 - 50
Stress 3 - 99.9 (or) 100

i missed the lecture and i again learned it completely here, great teaching.

[drtamalpramanick]

In stress calculation, how [B]= 1/L [-1 1] is coming? Basically how the row vector [-1 1] is coming? Kindly clarify.

[flexxytainment]

Love your work, great teaching.Thanks!!!

[bhaktigarje]

Sir from where this formula is derived?
(E/L1)[-1 1]{d3 d4}

[knowledgewithshoomans]

what we will do when we ask to consider two elements for each bar

[offroutemasti]

A coordinate is called simple natural coordinate if the values are between -1 and 1. That's why may be [B] matrix value is [-1 1].

[yaniv]

Very nice explanation! Thank you mate:👍

[taifshams]

Area 1 equals area 2 must be 100 mm square right since we have divided that body in 2 elements? I'm confused here.

[haridass.mmce-apmech]

Good approach to learners for ID problem..

[maheshwarthan]

You are the best compared to our professor

[saroj]

which book you are reffering nice work

[mr.kpadmanadham]

Well explained..concept is appreciable thank u

[wasimuddinpatel]

Can you explain Sigma 2 calculation cause I am getting 50 N/mm²

[anamlicha]

stress 2 =50 MpA and stress 3 =100.26MPA

[ammarshaikh]

31:10 correct ans is sigma 2 = 50N/mm sir
