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.

The correct answer is option D.
Fixed support in the real beam becomes a free end in the conjugate beam and vice versa.
Internal Hinge connection in real beam becomes simple support in conjugate beam and vice versa.
Simple support at the edge remains the same for both real and conjugate beams.
Fixed support in the real beam becomes a free end in the conjugate beam and vice versa.
Internal Hinge connection in real beam becomes simple support in conjugate beam and vice versa.
Simple support at the edge remains the same for both real and conjugate beams.

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.

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.
Simply Supported End- No Change.
Internal Hinge Becomes Internal Support and Internal Support becomes Internal Hinge.
So, the Correct answer is D.

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

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.
So, D is the correct option for this question.

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.

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

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

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