In case of conjugate beam fixed end becomes free and vice versa. Hinge. Remains same.

Shankar said: (Dec 27, 2013)  
Internal hinge becomes interior roller and vice versa in conjugate beam.

Mh.Haque said: (Jan 1, 2014)  
In case of conjugate beam fixed end becomes free and vice versa. Internal hinge becomes interior hinge/roller and vice versa.

Vijay said: (Jan 15, 2015)  
Fixed end become free and vice versa.

Hemendra said: (Jun 26, 2015)  
Answer should be D, as internal hinge becomes a roller and vice versa.

Vivek said: (Sep 3, 2015)  
End hinged support must become roller support.

Ankita said: (Sep 28, 2015)  
Answer should be D as internal hinge get replaced by roller.

Pankaj Barwal said: (Jan 15, 2016)  
The right answer is D.

Because in the case of conjugate beam:

A. Fixed end become free end.

B. Hinged end become roller end.

C. Simply support become hinged.

And last one is remain same.

Amruth said: (Mar 30, 2016)  
Option (D) should be the answer as internal hinge will get replaced by roller.

Pooja Patil said: (Jun 23, 2016)  
Option D is the right answer. Because internal hinge become roller.

Prithvendra Singh said: (Aug 30, 2016)  
Correct option should be D as in conjugate beam method, we replace intermediate free hinges by rollers and rollers by free hinges and if there is fixed joint at one end then it becomes the free end and vice versa and the hinge support at ends remain unchanged.

Snehal Wankhede said: (Aug 30, 2016)  
It is Option A.

Internal hinge (θ exist & δ exist) become external hinge (V exist & M exist respectively) in the conjugate beam.

Himanshu said: (Nov 21, 2016)  
D is 100% right answer.

Vishal Behl said: (Dec 4, 2016)  
D is correct one.

Neha said: (Jan 18, 2017)  
And what is c point?

Bhawna Gaur said: (Jan 24, 2017)  
Answer should be D because internal hinge becomes internal support.

Lukesh Kumar said: (Jan 26, 2017)  
I think the answer is D.

Asaithambi said: (Feb 9, 2017)  
Normally, conjugate beam fixed end is converted free end. Roller support is a shift to hinged point. So the answer is D.

Raj Ghusinga said: (Mar 21, 2017)  
D can't be the answer.

Because at support c there should be only angular disdplacement not linear displacement in conjucate beam.

Tiger Venkateshwar said: (Apr 7, 2017)  
In case of the conjugate beam, fixed end becomes free and vice versa and Hinge Remains same.

Duraisamy said: (Apr 12, 2017)  
Hinge means failure before to create a hinge.

Hinge is formed fixed and external load in maximum at mid point.

Sanket said: (Jun 5, 2017)  
The correct Answer should be D.

Rishu Raj said: (Jun 14, 2017)  
I think option A is correct, internal hinge change to internal support and roller=roller and hinge = hinge.

Durgesh Thakur said: (Jun 30, 2017)  
Answer is D because point c is roller and in conjugate beam roller is converted into hinge and hinge into roller and vice versa.

Surrendaren said: (Aug 5, 2017)  
The right answer is option D.

Vinay Singh said: (Aug 29, 2017)  
D should be right answer, because internal hinge become roller.

Prakash said: (Sep 18, 2017)  
Correct answer should be D.

Varsha Prasad said: (Oct 23, 2017)  
Correct answer should be A.

According to conjugate beam method the internal hinge of real beam support is change to interior support in conjugate beam support.

Jainul said: (Nov 4, 2017)  
Free end equals to fixed support.

Sheela said: (Dec 16, 2017)  
According to me, the Correct Answer is D.

Priyadharsini said: (Dec 20, 2017)  
The correct answer D.

"real support - conjugate support rule".
fixed support - free end.
middle hinge - middle support.
middle support - middle hinge.
hinged support - hinged support.

Mercyevanjaline said: (Jan 17, 2018)  
Option B is correct because fixed becomes the free end, hinge becomes hinge, and roller becomes a roller.

Marsimoyi said: (Jan 22, 2018)  
Answer should be D.

Because The conjugate beam for real beam If its fixed -free end and vice-versa. For internal hinge -internal roller support and vice versa.

Vinodh said: (Jan 26, 2018)  
Opt D is the right answer.

Surekha Mule said: (Feb 7, 2018)  
Option D is the correct answer.

Mujahid said: (Feb 18, 2018)  
No, the correct answer should be D.

Abc said: (Apr 5, 2018)  
Yes, The correct answer should be B. I agree with the given answer.

Vaish said: (Feb 24, 2019)  
Fixed becomes free.
Internal hinge becomes a roller.
Roller becomes an internal hinge.
Hinge is a hinge.

Bhutan said: (Aug 10, 2019)  
The Correct answer is A.

Rajdeep Singh said: (Aug 12, 2019)  
The fixed end becomes free, Free becomes Fixed.

Simply Supported End- No Change.

Internal Hinge Becomes Internal Support and Internal Support becomes Internal Hinge.

So, the Correct answer is D.

Preeti Yadav said: (Sep 5, 2019)  
Option D is the correct answer.

Preeti said: (Jan 16, 2020)  
The correct Answer should be D.

Pritam Saha said: (Feb 5, 2020)  
What is that at ''C'' in the main structure, Is it any kind of pin support?

Shiva Kumar said: (Aug 26, 2020)  
In a simple manner, the number Of equilibrium conditions are 4 in question those are verticle force horigentle force and moment and having hinge at B having a moment is zero. Compare the option with equilibrium conditions we get option B and D are matching but hinge will not change. So, option B is correct.

Rajesh Kumar said: (Jan 10, 2021)  
D is the correct option. Internal hinge is converted into Roller support. If not provide Roller support then the beam will rotate about a hinge.

So, D is the correct option for this question.

Umar said: (Jan 13, 2021)  
Option D is correct because in conjugate beam internal hinge repassed to roller & roller support hinge.
