Statically indeterminate problem 1 (English)

Problem:
A circular steel bar ABCD, rigidly fixed at A and D is subjected to axial loads of 50 kN and 100 kN at B and C. Find the loads shared by each part of the bar and displacements of the points B and C. Take E for steel as 200 GPa.

Answers:
P1 = 29.4 kN (T)
P2 = 20.6 kN (C)
P3 = 120.6 kN (C)
Displacement of B = 0.9 mm towards the right.
Displacement of C = 0.07 mm towards the right.

Guys...pls see that second eqn is actually p2-p3=100... I was saying it correctly... But written wrongly... So pls take care

This is the best (and only) explanation for a 3-section statically indeterminate problem like this that I could find on YouTube. Thank you so much.

How to get area to solve till final solution 😢

Sir pls check whether the answer for Exercise 4.1, Qsn. No. 4 is correct or not in RS Khurmi book. Please help.

E de unit etha edukande while solving?

[VS_]

This question is from which reference book

[shummunkhimhun]

Isn't tensile taken as positive and compression as negative.p1+P2=50

[banes]

Displacement of point b is Delta L1 but why at point c it's Delta L3....why can't it be Delta L2

[vishnur]

You have already said . P3-p2 =100 but, you wrote there is p2-p3=100.. that's little bit confused...

[beingdk]

Sir if 100kn is in the direction of P3, is the equation P3 - P2 = 0 right?

[VishwaGumnaam]

Thankypu so much teacher you explained it so easily really grateful

[banes]

Why p1 - p2 why can't it be in reverse form sir

[nanditmaheshwari]

Bro why did not you consider reaction forces ?

[nickjones]

It should be p2-p3 =100 na coz p2 and 100kn in same direction .why you changed it into p3-p2 ?
Can anyone explain this ?

[The_travellerrr]

if there was some expansion allowed then???

[rammeshadhavsr]

from which book this problem is taken??

[mohammedjensher]

it is more precious and good effort sir✌

Sir please upload- KTU - RAC - MECHANICAL - S7
