I have retired as Professor-Mechanical in Sri Venkateswara College of Engineering and Technology under Anna University affiliated colleges in Tamil Nadu, India. I have 19 years of Industrial and 20 years of teaching experience. I am learning Maple for the past four and half years hoping to make at least one appreciable maple presentation.

## Novice Attempt in Graph Theory...

Maple

I do not know! I am a novice in maple as well as in graph theory. I attach a doc in which i attempted to learn what is network. It seems alright with maple as it gives as what it understands as horizontal and vertical network. I do not expect a horizontal line as horizontal network and vertical line as vertical network, in which case a horizontal line with nodes 1 and 2 will be vertical network if  draw it vertically. The maple, in my opinion ( i am not a maple man) gives the answer in a vertical pattern, rightly so for clarity and space constraint.

I am sorry if i am confusing.  The document in my attempt to know more may give you also more insight. Thanks.

## What is my mistake?...

Maple

 Consider a taper steel plate of uniform thickness mm as shown in the Fig. In addition to its self weight, the plate is subjected to a point load N at its mid point. Find the global force vector [F] , global stiffness matrix [K] , displacement in each element (1 and 2) , stresses in each element  (1 and 2) and reaction force at the support.Take N/mm2; kg/m3;  =  =  =  = Revised areas:  =  =   m2; is support reaction N; N;  =   N/mm2  =  N/mm2 Number of elements,  = N/m ;  m;   elementsl   m; We shall consider a two element system as shown in the Fig. For element 1 Stiffness matrix K is                                              =    For element 2 Stiffness matrix K is                                            =    Global stiffness matrix obtained by adding all the elemental stiffness matrices and given b              =    For element 1 Load matrix F is    =   For element 2 Load matrix F is  =
