Solution of Non – linear equation in single variable using the Regula – Falsi, Newton –Raphson method.


Aim: - Solution of Non – linear equation in single variable using the Regula – Falsi, Newton –Raphson method.

ALOGRITHM:: -

Newton – Raphson Method: -
1.  Assign an initial value to x, say x0
2.  Evaluate f(x0) & (x0)
3.  Find the improved estimation of x0

 X1 = x0 – f(x1)/f (x0)
4.  Check the accuracy of the latest estimate.
Compare relative error to a predefined value E. if [(x1 – x0)/x1]<=E
Stop; otherwise continue.
5.  Replace x0 by x1 and repeat step 3 and 4.

Solution of Non- Linear Equation in single variable using the method of successive bisection.


AIM:- 
Solution of Non- Linear Equation in single variable using the method of successive bisection. 

ALGORITHM:- 
Bisection method. 

 1.  Decide initial values of a & b and stopping criterion, E.
2.  Compute f1 =f(a) & f2 =f(b)
3.   if  f1 * f2 >0, a & b do not have any root and go to step 7; otherwise continue. 
4.  Compute *x=(a+b) /2 and compute f0 =f(*x)  
5.  If f1 * f0 <0 then
Set b=*x
Else
Set a= *x
Set f1 = f0    
6. If absolute value of (b-a)/ b is less than error E, then 
    root=(a+b)/2
    write the value of root 
    go to step 7 
     else  
     go to step 4
7. stop

To prepare simple engineering component / shapes by forging.


Aim: - To prepare simple engineering component / shapes by forging. 

Material required:- M.S. rod of diameter 8 mm, for making ring.
M.S. square 16×16 mm for chisel. 

Tools required: - Steele scale, scriber, hand saw, cross cut file, furnace, hammer, anvil,
flat tong, and swage block.


Procedure for Chisel:- 

 1.  M.S. square of required length is to be cut. 
2.  One end of the piece is heated in furnace to red hot condition. 
3.  Hot piece is brought to anvil holding by a tong. 
4.  The piece is shaped using smith hammer. 
5.  If required the piece is reheated and the process is repeated.
6.  The piece is put in to water for tempering. 

Procedure for Ring:- 

 1.  M.S rod of required length to be cut. 
2.  The piece is heated in furnace to red hot conditions.
3.  Hot piece is held with a tong and brought to anvil. 
4.  The piece is shaped on horn anvil using hammer.
5.  If required the piece is re heated and the process is repeated.
6.  Complete round is made on swage block.
7.  The piece is put in to the water for tempering. 


Precautions:- 

Wear `apron, shoes, nose mask, gloves and tight fitted clothes.
Be careful and attentive while working on job of forging.
Hammering should be done only when the work piece is hot.
Always use appropriate tongs and tools. 



  

To prepare Joints for welding suitable for butt- welding and lap welding.


Aim: - To prepare Joints for welding suitable for butt- welding and lap welding.

Tool required: - Scale, scriber, hand hack saw, flat file, swing scale protector,

using file. 
3. Electrode is held in electrode holder and earth clamp is clamped to the work piece. 
4. Pieces are positioned properly butting each other and tack weld in done at two end
points.

Precautions:-
 Wear apron, shoes, nose mask, gloves and tight fitted clothes.
  Be careful and attentive while working on welding job.
  During welding don’t see the welding light rage directly without the goggles / face      
shield. 
Do not cool the welding piece in water.
Do not keep electrode holder on the welding machine.
No inflammable material should be present in welding shop.
