1]. The following variable is available in file1.c
static int average_float;
all the functions in the file1.c can access the variable

[2]. extern int x;

Check the answer

[3]. Another Problem with

# define TRUE 0

some code

while(TRUE)
{
some code

}

This won't go into the loop as TRUE is defined as 0


[4]. A question in structures where the memebers are dd,mm,yy.

mm:dd:yy
09:07:97

[5]. Another structure question

1 Rajiv System Analyst

[6]. INFILE.DAT is copied to OUTFILE.DAT


[7]. A question with argc and argv .

Input will be

c:\TEMP.EXE Ramco Systems India

}

2)****SHOULD LEARN C++(this is very very IMP,Based

3)YOU SHOULD PREPARE ONE FEM PROJECT AND TELL THEM
THAT AS YOUR OWN WORK(This will increase chance

F E M TEST

1)WHO USED THE TERM FINITE ELEMENT FOR THE FIRST TIME?
a)
b)
c) CLOUGH

2)DERIVE THE JACOBIEN |J| FOR BEAM ELEMENT WITH STRAIN
ENERGY?

(ANS:PROMLEM IS NOT CORRECT PLEASE DO NOT ATTEMPT)

3)FOR AN ELEMENT SIGMA Ni=1,WHICH TYPE OF ELEMENT IT IS?
a)
b)NATURAL CO-ORDINATE

(ANS 100% CORRECT)

4)TIMOSHENKO BEAM ELEMENT THEORY TO CONSIDER -- - - -?
a)
b)
c)SHEAR DEFORMATION

5)SHEAR LOCKING - - - - ?

(ANS IS VERY STIFF 'K')

6)MEMBRANE LOCKING

(ANS IS ARCH ELEMENT)

7)Ex(epsiolan x)=dU/dX,Ey=dV/dY,r(X,Y)=?(gama(x,y)=?)
(ANS IS dU/dY+dV/dX )
8)K=integral B(TRANSPOSE)*D*B FOR LARGE DEFORMATION
WHICH MATRIX WILL GET EFFECTED?

(ANS IS D matrix )100%correct

9)FOR PLANE STRAIN f(Ex,Ey,Ez,r(x,y) ) - - -

(ANS IS Ez=0)

10)SERENDIPITY ELEMENT IS

(ANS 8 NODED ELEMENT)
(The element which is having nodes only on boundary is
called SERENDIPITY element)

11)IF THE ROTATION OF ELEMENT AND THE DISPLACEMENT ABOUT
N-A IS SAME THEN THE ORDER OF CONTINUITY

(ANS IS C1)

12)FRONTAL THEORY IS APPLIED FOR
(Please refer any fem book)

13)MINDLINS THEORY IS APPLIED FOR

c) this is the answer(Both Co&C1problems)

14)X=SigmaNi*Xi,U=sigmaNi*Ui WHICH TYPE OF ELEMENT
(Refer book)

15)BEAM SUBJECTED TO UDL FIND THE MOMENTS AT THE 2 NODES

16)Integral B(Transpose)*sigma(here sigma means stress)*dV
REPRESENTS?

(ANS IS INTERNAL LOAD VECTOR)

17)Integral ET(epsiolan transpose)*sigma*dV
P=strain displacement vector
Q=stress-strain deformation
Find [K]

(ANS [K]=[P]T(p transpose)*[Q]*[P] )
